Stretchy Washable Battery Now Closer For Wearable Devices

December 29, 2021 | Leave a Comment

University of British Columbia researchers have created what could be the first battery that is both flexible and washable. In addition to watches and patches for measuring vital signs, the battery might also be integrated with clothing that can actively change color or temperature. It works even when twisted or stretched to twice its normal […]

Stretchable Compressible Wearable Supercapacitors

July 6, 2017 | 1 Comment

Chinese scientists have introduced an extraordinarily stretchable and compressible polyelectrolyte. The new electrolyte when combined with carbon nanotube composite paper electrodes, forms a supercapacitor that can be stretched to 1000 percent in length and compressed to 50 percent in thickness without gaining and not losing capacity. The potential for flexible, wearable electronics that require equally […]

Electricity Production From Body Heat

September 13, 2016 | Leave a Comment

North Carolina State University researchers have developed a new design for harvesting body heat and converting it into electricity for use in wearable electronics. The experimental thermoelectric generator prototypes are lightweight, conform to the shape of the body, and can generate far more electricity than previous lightweight heat harvesting technologies. The researchers also believe they […]
