Cmos VI Bration and Solar Energy Harvester

Approaches to integrate vibration and solar energy harvesters with standard CMOS ICs are proposed. By using these methods, the ambient energy can be harvested by the integrated devices and converted to the electricity required by the circuits. The targeted energy forms are the vibration and solar energy. A new vibration energy harvester is proposed for low–frequency vibration mode. Different from the conventional vibration energy harvester, the proposed one will be more practical for use. In order to enhance the energy storing efficiency, a dye-sensitized solar cell is also to be integrated. By the combination of these two kinds of energy, it is anticipated that the future CMOS ICs can operate by itself without energy capacitors such as the batteries. The prospect of this proposal is to demo this idea with an ultra-low power integrated circuit and show its impact to the green energy industry as well as the IC foundries.
