Vibration Powered Batteries - Shake Up Some Electricity
Brother unveiled, on July 16, prototype vibration powered batteries for applications under 100MW. Actually a small generator, the company has named the device a "Vibration Powered Generating Battery."
Demonstrating one application in a remote control, a spokesman showed how simply shaking the unit for a few seconds created sufficient electricity to power the desired devices. An average remote control requires from 40-100 mW, and does not require constant power, making it an ideal candidate for the vibration powered batteries.
Batteries are ubiquitous in standard sizes, and Brother has packed their vibration powered generator in cases comparable to AA and AAA batteries. Such foresight guarantees an instant market without re-tooling electronics to accept the new batteries.
The vibration powered batteries employ an electromagnetic induction generator with a double layer electric capacitor. Capacitance is 500mF, output 10-100mW (for AA size), at 4-8mHz frequency.
See the Vibration Powered Generating Battery at Techno-frontier 2010, in Tokyo (July 21-23). The innovative batteries will be demonstrated powering two types of remote control, and an LED flashlight.
The reduction of hazardous waste will be an immediate benefit when the generating batteries reach the consumer market.
