Skin patch turns friction into electricity to power wearables
This is awesome:
One surface of the device is attached to the skin, while the other is covered in silicon with a gold film underneath. Sandwiched in between the two are tiny pillars of silicone rubber — slimmer pillars lead to bigger output, since they allow a larger surface area to touch the skin.
After attaching the patch to one's forearm and then to one's throat, they found that clenching your fist and talking generate 7.3 and 7.5 volts, respectively. Tapping it with a finger, though, produces 90 volts or enough energy to power several commercial LED lights.
