Nano-Wires
Scientists are using nano-wires to engineer small generators to power nano-devices of all kinds and which might eventually replace batteries, generating electrical power using your movements or body heat.
The nano-wire generator consists of zinc oxide nano-wires lined up inside a special electrode. The nano-wires are sent into movement by forces such as ultrasonic waves, mechanical vibration, blood flow, or even movements such as walking.
Elsewhere, scientists are using nano-wires to convert heat energy into electricity. "Rough" silicon wires, produced by a process known as "electroless etching," are utilised due to the thermoelectric efficiency across their surface.
