Battery technology has recorded some pretty impressive leaps forward over the past couple of years, modern power packs allowing users to easily recharge in a fairly short period of time, and even in the absence of a power source (there are plenty of solar-powered chargers available out there). However, it seems that Brother has actually managed to find an even easier way to recharge batteries, namely by simply...shaking them.

As TechOn informs us, the battery in question is called the "Vibration-powered Generating Battery” and can can be used for a device that does not always consume electricity and has a power consumption of about 100mW.

The company prototyped the generator in AA and AAA sizes. Inside a battery-shaped case, there are an electromagnetic induction generator and an electric double layer capacitor with a capacitance of about 500mF. The average output of the AA-size generator is 10 to 180mW (frequency: 4-8Hz).

Of course, Brother has not yet provided any information regarding just how long we'll have to wait before these things will start to be mass produced and marketed, but given the fact that they will prove to be extremely useful in saving power, we sure hope that they'll hit the shelves sooner, rather than latter.



We are just a few, but there are many of you, Softpedia users, out there. That's why we thought it would be a good idea to create an email address for you to help us a little in finding gadgets we missed. Interesting links are bound to be posted with recognition going mainly to those who submit. The address is .
