Brother Industries Ltd, a Japan based electronics firm has showcased vibration-harvesting generator that is capable of delivering power after a vigorous shake.

The Vibration Energy Cell batteries based on the technology could replace AA or AAA batteries in some of the devices. The batteries are based on Faraday’s Principle of Electromagnetic Induction to generate electricity.

The company showcased the device powered a TV remote control, a remote switch for a lamp and an LED torch at the Techno-frontier 2010 exhibition in Tokyo this week.

The device uses similar mechanism than that of a bicycle light dynamo while the Vibration Energy Cell batteries convert energy to power with a few shakes. The two AA-size generators give an out put of 3.2V or lower and thus limit its use.

A company spokesperson said, "Our Vibration Energy Cells generate electricity using a coil, a magnet, and condenser that charges electricity. These are all embedded in the battery... Because of its low output this type of cell is designed to be used for things such as TV remote controls and LED devices, which consume low power and do not consume electrical power continuously."

The spokesperson also expressed that the batteries are still under testing phase and the company has not yet devised a business plan for the product but it will continue to monitor market conditions and prepare a business plan.
