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'.

So a coat it silly, but what about...?

While I agree that putting the fabric inside a coat demonstrates a naive view of human factors (you can't wash the coat, you have to wear it all the time, etc.), I wonder if this might simply be the first idea they had after developing the invention?

Fabric generating power from movement would seem to have applications in other places: sails on boats; flags flying on buildings; tarpaulins on trucks, maybe quite a few others if the fabric is sufficiently robust enough.

if it was that efficient, they would have chosen a windmill demonstrator.

it's not that efficient, so they chose this demonstrator. if it provided enough power to charge a phone, they would have had that on the demonstrator. all their uses could be done with a tiny solar cell.
