Japanese electronics manufacturer Brother is stepping outside its printing and sewing machine roots to explore motion-powered battery technology. The Japanese company is unveiling prototype AA and AAA batteries that are comprised of a rechargeable battery and an accompanying generator which produces power from vibrations/movement. The system can generate up to 180mW and is designed for low power devices like remote controls and LED flashlights. No word on when, or even if, these batteries will hit mass production but folks in Japan can get a sneak peek at this shake and charge battery system during the upcoming Techno-frontier 2010 being held July 21 to 23 in Tokyo.
