We study on energy harvesters that produce electrical power from environmental vibrations through the MEMS (micro electro mechanical systems) mechanisms combined with ionic material technology, thereby targeting a 10 mW class power package needed for wireless sensor nodes of the next generation. A novel energy-harvesting device is developed by using the static induction current from electret (permanent charge) which is coupled with an electrical double-layer capacitor of ionic liquid.
