Self-Charging Batteries Powered by Vibration

Illustration for article titled Self-Charging Batteries Powered by Vibration

Brother Industries has developed an AA battery sized generator powered by vibration, which can be used to charge another AA battery. Shaking your remote every once in a while could soon be all that's needed to keep it alive.


Inside the generator battery sits an "electromagnetic induction generator and an electric double layer capacitor" and although you'd have to do an impossibly vigorous amount of shaking to power a DSLR, for low-drain gadgets like remotes and LED torches a quick shuffle should dribble out enough energy for a brief spell of use.
