Smart Contact Lens Detects Diabetes and Glaucoma – IEEE Spectrum

http://spectrum.ieee.org/nanoclast/semiconductors/materials/smart-contact-lens-detects-diabetes-and-glaucoma In research described in the journal Nature Communications, the UNIST researchers used graphene-nanowire hybrid films to serve as conducting, transparent, and stretchable electrodes.  Both the graphene and the silver nanowires contribute indispensible properties. This contact lens should be able to pick up indictors for intraocular pressure, diabetes mellitus, and other health conditions, according to the researchers. Add →

Using a supercapacitor for power management and energy storage in IoT

http://www.edn.com/design/power-management/4458294/Using-a-supercapacitor-for-power-management-and-energy-storage-with-a-small-solar-cell–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells.  Depending on the light level, whether indoors or out, small solar cells may deliver →

IoTuesday: Maximize Your WiFi!

https://www.sparkfun.com/news/2363 Interesting looking project: mount the antenna and ESP8266 Thing Dev Board onto a pan/tilt bracket with some servos. The ESP8266 code was updated to connect to a WiFi access point (AP) and begin sweeping up and down (about 70°) and left to right (about 180°). At 5° increments, the ESP8266 would take an RSSI reading. Finally the antenna automatically returns →
