Most powerful millimeter-scale energy harvester

Electrical engineers at the University of Michigan have built a device that can harness energy from vibrations and convert it to electricity with five to 10 times greater efficiency and power than other devices in its class. And it’s smaller than a penny.

This new vibration energy harvester is specifically designed to turn the cyclic motions of factory machines into energy to power wireless sensor networks. These sensor networks monitor machines’ performance and let operators know about any malfunctions. [via]
