We are living in the middle of the emergency over coronavirus all over the world. The reactions to the COVID-19 pandemic and its effects on societies and economies around the world cannot be understated. Because an estimated 15% of COVID-19 patients require hospitalization and 5% require intensive care (Z. Wu and McGoogan 2020), the ongoing COVID-19 pandemic has the potential of posing a substantial challenge to medical systems around the world (Remuzzi and Remuzzi 2020; Grasselli, Pesenti, and Cecconi 2020).
Necessity is the mother of invention. A need or problem encourages creative efforts to meet the need or solve the problem. This saying appears in the dialogue Republic, by the ancient Greek philosopher Plato.
“Necessity is the mother of invention” is an English-language proverb. It means, roughly, that the primary driving force for most new inventions is a need. When the need for something becomes imperative, you are forced to find ways of getting or achieving it.
Here are some examples of sort of ingenuity we need now in the middle of pandemia. Already many people contributed those efforts. Check out on those links what is already done if you can find any useful information or can contribute to those efforts you see as good idea. Start your reserach with 7 open hardware projects working to solve COVID-19 article.
I have collected here a list of interesting open hardware project and instructions that can be useful or educational. Hopefully this list I have contributed here will be useful for someone. Keep in mind that many of those ideas are potentially dangerous if the instructions are not entirely correct, implemented exactly right and used by people that know what they are doing. You have been warned: Do not try those at home yourself! We are dealing here with things that can easily injure or kill someone if improperly implemented or used – but at right place the best ideas from those could potentially save lives.
Repairing hospital equipment
The right thing to do in his situation is that medical companies to release service manuals for ALL medical equipment so they can be repaired and maintained where they are most needed.

Robotics
COVID-19 pandemic prompts more robot usage worldwide article tells that the coronavirus has increased interest in robots, drones, and artificial intelligence, even as some testing of autonomous vehicles pauses on public roads. It is believed that these technologies can help deal with massive staffing shortages in healthcare, manufacturing, and supply chains; the need for “social distancing;” and diagnosis and treatment.
Here are some robotics related links that could be useful:

Ventilators
A ventilator is a machine designed to provide mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Ventilators are sometimes colloquially called “respirators”.
A ventilator, also called a respirator, is designed to provide mechanical ventilation by oxygen into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. The machines can be used to help a person breath if they have conditions making it difficult to breathe, such as lung diseases, during and post-surgery. For patients critically ill with coronavirus access to a ventilator could be a matter of life or death.
In its simplest form, a modern positive pressure ventilator consists of a compressible air reservoir or turbine, air and oxygen supplies, a set of valves and tubes, and a disposable or reusable “patient circuit”. Modern ventilators are electronically controlled by a small embedded system to allow exact adaptation of pressure and flow characteristics to an individual patient’s needs.
They work by placing a tube in a person’s mouth, nose or small cut in the throat and connect it to a ventilator machine. The air reservoir is pneumatically compressed several times a minute to deliver room-air, or in most cases, an air/oxygen mixture to the patient.
Because failure may result in death, mechanical ventilation systems are classified as a life-critical system, and precautions must be taken to ensure that they are highly reliable. Modern commercial ventilator is a relatively complex piece of equipment with lots of components and a dedicated supply chain.
Because there is a lack of ventilators on many hospitals in several countries, there has been a lot of creative work done to help this problem.
There has been projects going on to repair old and non-working ventilators to a working conditions. For repairing some older devices, there has been problem to get spare parts from the manufacturer and that those spare parts can be very expensive. Also getting the service information for repairing those equipment seems to be hard to get from manufacturer, Ifixit has started a project Help commit industrial espionage for the greater good! to get the service information on-line at https://www.ifixit.com/News/36354/help-us-crowdsource-repair-information-for-hospital-equipment
In middle of the emergency some people have worked on to make their own spare parts when official parts are not available, thus making more devices available. For example a startup 3D-printed emergency breathing valves for COVID-19 patients at an Italian hospital in less than 6 hours. An Italian hospital that ran out of life-saving equipment for coronavirus patients was saved by a ‘hero’ engineer who used cutting-edge technology to design oxygen valves within a matter of hours. At least 10 lives were saved in this way.
So great thinking for 3d printing of valves. Are they sterilized and suitable? 3D printing has been used in numerous cases for medical parts already. Most 3D printing operates at relatively high temperatures and printed objects are actually naturally sterilized when they are made. Anyway the right kind of plastic needs to be selected and the part needs to be built in exactly right way that is works reliably as designed. If they are used and the individual gets worse, does the fact that equipment not medical certified (environment, storage, shipping, etc) put the hospital in additional jeopardy for a lawsuit? All valid questions each medical liability officer will have to address. But if people are going to literally die if you do nothing, then taking a risk with a part that you 3D print seems like an idea that is worth to try.

Another tried trick is try to use one ventilator with more than one patient. Daily Mail writes that ventilators can be modified to help FOUR coronavirus patients breathe at the same time if the NHS is still critically short of the machines when the outbreak peaks, scientists say. Here are some links to material on using one ventilator to more than one patient:

Testing for infection
There are many approaches thought to be helpful to finding out if someone is infected or something is contaminated.
Thermal scanners are effective in detecting people who have developed a fever (i.e. have a higher than normal body temperature) because of infection with the new coronavirus. However, they cannot detect people who are infected but are not yet sick with fever (it can take 2-10 days before infected people get the fewer).

Prevent touching face
It is recommended to stop touching your face to minimize spread of coronavirus and other germs. People touch their faces frequently. They wipe their eyes, scratch their noses, bite their nails and twirl their mustaches.
Not touching your face is a simple way to protect yourself from COVID-19, but it’s not easy. If you can reduce face-touching, you can lower people’s chances of catching COVID-19. Why is it so hard to stop? Face-touching rewards us by relieving momentary discomforts like itches and muscle tension.
If you you want to change, you can try to replace it with a competing response that opposes the muscle movements needed to touch your face. When you feel the urge to touch your face, you can clench your fists, sit on your hands, press your palms onto the tops of your thighs or stretch your arms straight down at your sides. Some sources recommend object manipulation, in which you occupy your hands with something else. You can rub your fingertips, fiddle with a pen or squeeze a stress ball.

Hand sanitizer
Hand sanitizer is a liquid or gel generally used to decrease infectious agents on the hands. It depends on the case if hand washing with soap and water or alcohol-based hand sanitizer is preferred. For Covid-19 WHO recommends to wash your hands with soap and water, and dry them thoroughly. Use alcohol-based handrub if you don’t have immediate access to soap and water.
It seems that there are many places where there is shortage of hand sanitizers. This has lead to situation where people have resorted to making their own. Recipes for DIY hand sanitizer are popping all over the internet. A quick search reveals news articles, YouTube how-to’s and step-by-step visual guides. But think twice about joining them — experts are wary and even caution against the idea. The World Health Organization even has an official guide to making hand sanitizer. But it’s intended for populations that do not have clean water or other medical-grade products in place. Don’t try to make your own hand sanitizer just because there’s a shortage from coronavirus.

“Every time a new health incident occurs there’s a rush on hand sanitizers, often causing shops to sell out.

Sanitizing things
With deadly coronavirus spreading worldwide at an alarming speed, personal hygiene has become paramount importance to contain the infection spread further. Mobile phones are known to house several germ, and if you thing they are contaminated, you should maybe disinfect them. The CDC recommends that everyone “clean all “high-touch” surfaces every day” to protect against the spread of COVID-19.
How to Disinfect Your Smartphone article says CDC recommends that for your smartphone you should use 70% rubbing alcohol or alcohol-based disinfectant spray to wipe down the back and sides of your device. For example Apple recently updated its official cleaning advice, so ccording to Apple, it’s now safe to clean your iPhone with disinfecting wipes if you do it correctly. You should not try to spray any liquid to your phone.
The other option is to use a smartphone sanitizer device that cleans using UV rays. Sanitizers that use ultraviolet (UV) rays to kill bacteria and viruses have been around for a while now and they can kill 99% of bacteria in as little as five minutes. However its efficacy hasn’t been tested against nasties like SARS-CoV-2, the virus responsible for COVID-19. Coronavirus effect: Samsung offers UV-C sanitizing service for Galaxy devices. Samsung is using Ultraviolet germicidal irradiation (UVGI) disinfection technology, which uses of uses short-wavelength ultraviolet (UV-C) light to kill or inactivate bacteria, virus, molds and other pathogenic microorganisms on smartphones.
The UV-C light is capable of destroying nucleic acids and DNA. It will kill many things, but you don’t want that hitting your eye or skin. World Health Organization only states: “UV lamps should not be used to sterilize hands, or other areas of skin as UV radiation can cause skin irritation.”
Here are some UV C related links:

Protective masks
The protective mask ratings used by hospitals are typically N95, FFP2 or FFP3. FFP2 protection level is 94%. FFP3 protection level is 99%. N95 protection level is 95%. An N95 FFR is a type of respirator which removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3 micron) particles. N95 FFRs are capable of filtering out all types of particles, including bacteria and viruses. The N95 mask is mainly for use if you already have the virus to keep it from spreading and many have argued that coronavirus is smaller than the 0.3 micron filter rating of the mask and thus, not that helpful, for people outside of healthcare. In fact, the U.S. Surgeon General wants consumers to stop buying masks.
Due to the worldwide pandemic of COVID-19, there has been a huge shortage of N95 masks. Promoting simple do-it-yourself masks: an urgent intervention for COVID-19 mitigation claims that widespread use of masks by the general population could be an effective strategy for slowing down the spread of COVID-19: “Since surgical masks might not become available in sufficient numbers quickly enough for general use and sufficient compliance with wearing surgical masks might not be possible everywhere, we argue that simple do-it-yourself designs or commercially available cloth masks could reduce the spread of infection at minimal costs to society”.
With masks sold out during the coronavirus outbreak, many people will have to make do with what some scientists have called “the last resort”: the DIY mask. Many people have been working on designs for a DIY mask that may be able to protect those who haven’t been able to secure their own masks. It seems that cotton homemade masks may be quite effective as alternatives and there are also other ideas. For any DIY ideas, be warned that there is no guarantee that those designs are effective. So I don’t recommend to use them as alternative to proper mask when they are available. Bit of proper marks are not available, they can be better than nothing.
Keep in mind the right filter type to use: Hepa filters do have the ability to filter particles and viruses, but they wont protect you 100% of the time. The real secret is layers. The problem is, more layers, more restriction. Keep in mind that charcoal filters will make your air fresher, but have almost no effect on cleaning the air of viruses. Coronavirus virions (or ‘particles’) are spherical particles with diameters of approximately 125 nm (0.125 microns). The smallest particles are 0.06 microns, and the largest are 0.14 microns. This means coronavirus particles are smaller than PM2.5 particles, but bigger than some dust particles and gases.

“According to a studied performed at Cambridge University during the 2009 H1N1 flu pandemic, while surgical masks perform the best at capturing Bacillus atrophaeus bacteria (0.93-1.25 microns) and Bacteriophage MS virus (0.023 microns), vacuum cleaner bags, tea towels, and cotton T-shirts were not too far behind.

https://smartairfilters.com/en/blog/diy-homemade-mask-protect-virus-coronavirus/
“DIY masks to protect against from viruses sounds like a crazy idea. Data shows masks work incredibly well, and they’re also really cheap. Surgical masks cost a few pennies, and they’re capable of filtering out 80% of particles down to 0.007 microns (14 times smaller than the coronavirus).”
“The homemade cotton masks captured 50% of 0.02-1 micron particles, compared with 80% for the surgical mask. Although the surgical masks captured 30% more particles, the cotton masks did surprisingly well. The researchers concluded that homemade masks would be better than nothing.”
“The Cambridge data shows that homemade masks made using cotton t-shirts can filter out some particles that are 0.02–1 microns in size. That’s pretty good, however its only one test.”

The project is released under an open-source license and has been simultaneously patent pending to prevent other entities from commercializing it.”
“Copper 3D team quickly got to work on developing the patent for a model similar to a standard N95 mask but with some peculiarities (Antiviral, Reusable, Modular, Washable, Recyclable, Low-Cost), which were completely designed in a digital environment so that it could be downloaded anywhere in the world and 3D printed with any FDM/FFF equipment, even a low cost one.

1) Social distancing automated
Start with social distancing, where engineers are trying to develop people counters for places like retail stores by combining photoelectric proximity sensors with miniature programmable logic controllers (PLCs). Here, while proximity sensors detect the direction of movement, PLCs can calculate the number of people in and out of the store in real-time.
2) COVID-19 testing with cameras
Coronavirus testing is a major challenge for healthcare organizations around the globe, and a lot is going on in this space, especially for finding efficient ways for contactless temperature measurements carried out in an automated fashion.
3) Pre-diagnostic screening
Engineers are also busy acquiring cough sound samples from volunteers and analyzing the datasets to identify unique cough patterns associated with COVID-19 infections.
4) Wireless patches for contact tracing
The wearable self-monitoring solutions are going to be critical in contact tracing and exposure notification systems.

The Foundation for Innovative New Diagnostics, or FIND, headquartered in Geneva, Switzerland is currently evaluating 41 rapid COVID-19 tests. So far only one passes muster. “People in low- and middle-income countries often do not have access to laboratories,” says Jilian Sacks, FIND’s COVID-19 Evaluation Programme Lead. “So the ability to have rapid tests, especially outside the hospital and in decentralized settings, is most critical moving forward. But we are seeing that there is a lot of variability in the performance of rapid tests,” she says.

We’re all impatient for solid recommendations based on rigorous testing and established facts, but in a fast-moving field, that’s rarely possible. And someone always has to be the guinea pig. This was just as true 130 years ago when Niels Ryberg Finsen began experimenting with treating disease with UV light. He started by testing on himself.

https://spectrum.ieee.org/news-from-around-ieee/the-institute/ieee-member-news/this-wearable-monitors-the-wellbeing-of-senior-citizens-who-selfisolate-during-the-pandemic
Because senior citizens are at a higher risk of suffering serious complications from COVID-19, medical officials have cautioned them to stay at home. Their family and caregivers have also cut back on visits due to fear of spreading the virus to them. This situation has left many of the elderly increasingly isolated and without anyone to keep a watchful eye on their health.
A team led by electrical engineer Rogerio Dionisio at the Polytechnic Institute of Castelo Branco, in Portugal, has created a wearable monitoring system that keeps track of a person’s daily routine and alerts caregivers if it suspects something is amiss.

ABOUT THIS PROJECT
Overview
The pandemic has introduced a constraint to social interaction: distance. Considering this factor of risk, countries all over the world have been in varying levels of quarantine, and many malls have had to close down due to significantly lowered consumer count. This has led to a very, very high level of layoffs of mall personnel, as well as similar economic challenges for business owners.
This has caused relative low-income (less than $40,000 in annual earnings) job loss levels as of July 2, 2020 in the US due to COVID-19. Accommodation and Food Services, as well as Retail Trade and Entertainment collectively count for ~4,000,000 of the estimated jobs lost.
The economic challenge faced by different industries, where Food, Consumer, and Retail come up in the Top 6 industries with the highest number of employees laid off (amounting to estimated 20,000+ jobs). Assuming “International” to include for all non-US areas taken into account by this research, the total global layoff count reaches an estimated 103,000+ jobs.
COMPLICATION
Considering the given data, the team has determined a major challenge to be that there is risk uncertainty, with regard to population density in different shops, for the malls that are still open. Aside from this, while wearing face masks and avoiding touch is mandatory in many places, there are still violations. This makes it more difficult for those mall personnel and business owners, who cannot afford to work remotely, to safely navigate this new normal workspace. This begs the question: how can we guarantee to a decent certainty level that, at any point in time, a particular shop in the mall is safe to enter?
We all are now fighting against the prevailing COVID-19 pandemic. And also, now we are in a situation where we have to adapt to the prevailing conditions with more safety measures. While life coming back to normal with more safety measures to avoid virus infection, adding safety within the public places and crowded areas are also prevailing in the cities. But there were many situations where we have to break the safety measures and interact with an unsafe element to meet the needy. Here, the project is dealing with the prevention of COVID-19 spread though touch interactions or touches.
An experiment had been conducted to see the spread of any Virus through touch. The results were evaluated as follows:
Hence I decided to automate the most commonly used devices in housing and societies to ensure hands-free communication with devices.
The following solutions were developed in making this prototype
Smart Intercom System using TinyML deployed on Arduino33 BLE Sense: The following will be a touch-free solution using Computer Vision and a TinyML model to detect a person outside the door and conduct a bell ring without the person touching the bell.
TemperatureMonitoring system Using IoT and alert system : Amidst the pandemic, safety has become an important aspect. Hence, the Temperature Monitoring system utilizes IoT Thingspeak dashboard and detects people while entering and measures their temperature. This temperature is displayed to an IoT Dashboard for timely trends and data analysis.
Touch-Free elevator system using Speech Recognition TinyML model on Arduino BLE 33 sense: We use lifts to go up or down in a building several times a day, and I always have a fear of touching contaminated switches which have been touched by other people commuting. Hence this speech recognition model will identify when a person wishes to go up or down and similarly will perform the action.
MaskModel Detection System based on TinyML and IoT monitoring system : This method will use a computer vision model deployed on Arduino BLE 33 sense to detect whether a person has worn a mask or not and similarly this data is sent to an IoT Dashboard
Smart Queue monitoring and establishing system in a supermarket or a mall using TinyML, IoT and computer vision: This model will detect a person standing outside the supermarket and allow the entry of 50 people at a time in the supermarket.
Person Monitoring System in an Aisle in a Mall and contamination based Sanitization System: This solution Uses Person detection Algorithm deployed in an area in a Mall or a supermarket and if the person contamination in an area has passed the threshold, It self sanitizes the area with UV light. The Sanitization period and times is projected on an IoT Dashboard for the supermarket staff for analysis.

The current One-Way Willie is a simple, yet effective, prototype. If I were to win a Newark hardware voucher, the assistance of Dragon Innovation, and product marketing on Hackster.io, I would be able to develop it into a full, human-scale product, as well as considerably enhance the detection and discouragement techniques employed.
Additionally, the MKR’s onboard Wi-Fi capabilities will allow me to incorporate MQTT via AWS IoT Core, as I have in other projects, enabling Willies to send analytics data to the cloud, as well as perhaps even coordinating responses to violators!!!

Apple’s contact-tracing technology, developed with Google, relies on Bluetooth smartphones technology to notify people when they come into close contact with a person who’s tested positive for COVID-19. Until now, however, iPhone users could only turn on the exposure notifications if they also had a contact tracing app developed by a public health authority. Apple and Google have said they won’t retain any health data.

With the COVID-19 pandemic in mind, a team from MIT developed an open source wearable hand sanitization device that you can build yourself.
Germ theory has been widely accepted since the late 19thcentury and everyone alive today has grown up with the knowledge that sanitation is important in the fight against communicable disease. We all know that we should be washing our hands after using the restroom, handling raw food, and so on. But it has taken a worldwide pandemic to make us realize just how quickly and easily disease can spread when we’re not careful. With that in mind, a team from the MIT Media Lab developed this open source wearable hand sanitization device that you can build yourself.

COVID-19 tracing without an app? There’s an iOS and Android update for that
Google and Apple’s new ‘Exposure Notifications Express’ gives health authorities a shortcut
https://www.theregister.com/2020/09/02/google_apple_exposure_notifications_express/
Google and Apple have updated their COVID-19 contact-tracing tool to make it possible to notify users of potential exposures to the novel coronavirus without an app.
The new Exposure Notifications Express spec is baked into iOS 13.7, which emerged this week and will appear in an Android update due later this month.
This is not, repeat not, pervasive Bluetooth surveillance. The tool requires users to opt in, although public health authorities can use the tool to send notifications suggesting that residents do so.
