Miniature Power-Storage Solutions to Activate Sensors and Wireless Devices

Murata has developed two ultra-small energy-harvesting  systems for supplying power to sensing devices and wire-free elements by eliminating the necessity of an exterior electricity provision.

One of the systems will produce electricity from feeble vibrations and the other system will generate power from dim light sources, and the operation is based on the working of its earlier devices, which creates power from temperature deviations and from a piezoelectric component to transform pressure to electricity.

The two systems will be marketed from 2011, and Murata anticipates that their products will have a broad utility in industrial equipment and automotive firms.

The light-enabled energy harvesting  system employs an organic component to capture and transform light energy. This process inturn will produce 100 µW from a light source with 400 lux. The power/current will build up in a capacitor, in order to provide sufficient watts of power to activate the sensing devices and wire-free elements incorporated into the module.

The vibrational energy harvester  is capable of producing 100 µW of energy if shaken lightly by hand. Nikkei Business Daily reports that Murata will publish additional specifications about its products and will initialize the production process by 2011.
