Researchers create stretchable super capacitors for our next wearables


Carbon nanotube forests improve the stretchable supercapacitor’s performanceDuke University

The supercapacitors still functioned well when stretched to eight times their original size.

Imagine a new type of supercapacitor that can be repeatedly stretched to eight times its original size, yet still retaining its full functionality. Only after 10,000 cycles of charging and recharging does it start to lose a little percentage of its energy performance.

Researchers from Duke University and Michigan State University (MSU) have done just that. The team sees their novel supercapacitor as part of a power-independent, stretchable, flexible electronic system that could be used in wearable electronics or biomedical devices.

The Band-Aid of the future knows when you’re healed


The Band-Aid of the future knows when you’re healed

 It’s easy to imagine these wearable circuits on the shelves of CVS.

The Apple Watch is an enticing product, but it hasn’t revolutionized personal health the way its cheerleaders have promised. It can track steps, but it can’t see how your body is moving. It can measure your heart rate, but it can’t see how you are healing. The Apple Watch really only scratches the surface of what we imagine for intimate, wearable electronics.

But a new research project out of Carnegie Mellon is nearly as easy to put on as an Apple Watch and a whole lot more capable and customizable. Dubbed ElectroDermis, it’s a spandex bandage topped with stretchable, electric wiring and the sorts of circuits and sensors you find in any mobile electronic. “We were inspired by traditional medical bandages, as they come in a variety of shapes and sizes, soft and conformal, and can be placed anywhere on the body” for more accurate readings, says the paper’s co-lead Eric Markvicka.
