Stretchy batteries – made with origami technique – could power wearable electronics

Stretchy batteries inspired by origami could power smartwatches and other wearable electronics, researchers say.

Increasingly, scientists worldwide are developing flexible electronics, such as video displays and solar panels, that could one day make their way into clothing and even human bodies. But one limitation of these devices is the scarcity of equally flexible batteries to power them or store energy they generate.

Although prior research has created bendable batteries, it has proven more challenging to developing ones that are stretchy versions has proven more challenging, researchers said. Now, inventors have created lithium-ion batteries that can stretch to more than 150% of their original size, while remaining capable of powering devices Read more...
