Principle of Operation of the Proposed Energy Harvester (IMAGE)
Caption
When the capacity of the tunable capacitor is higher than that of the electret circuit, a movement of charges is induced in one direction. Likewise, when the situation is reversed, a movement of charges is induced in the opposite direction(Above). Pictures of the system and measured voltage output. To the left, pictures of the designed system are shown; the comb-like structure of the MEMS tunable capacitor can be appreciated. To the right, the measured voltage output demonstrates that mechanical vibratory energy can be effectively harvested (Below) .
