Energy-Generating Fabric Set To Power Battery-Free Wearables

An anonymous reader writes A team of researchers in Korea and Australia have developed a flexible fabric which generates power from human movement – a breakthrough which could replace batteries in future wearable devices. The effect of the fabric's nanogenerators mirrors static electricity with the two fabrics repeatedly brushing against each other and stealing electrons from the one another – this exchange creates energy from the wearer's activity without the need for an external power source. During testing, the researchers demonstrated the nanogenerator powering a number of devices such as LEDs, a liquid crystal display, as well as a keyless car entry system embedded in a nanogenerator 'power suit'.

Just give us a better battery.

I'm surprised no one ever thought of this. What are they thinking?? I mean, it seems so obvious.
