MicroGen has developed a “piezo-MEMS” (piezoelectric microelectromechanical systems) device that gathers ambient vibrations and converts them into electrical energy.

Vibration causes a tiny flap in the device to swing back and forth, generateing electrical current that charges an ultra-capacitor (a thin-film battery).

The “BOLT micro-power module” (MPM) begins commercial-scale production in summer 2013. It was researched and developed by the company at the… Read more
