Abstract: By combining energy generation and energy storage, the microPowerChip provides a unique solution for power in inaccessible or remote microsystems. The energy generation units can convert ambient energy into electrical energy using proprietary conditioning circuitry and store it in a volumetric microbattery or micro-supercapacitor. Microsupercapacitors have a high power density and can withstand thousands of cycles.

Micro-batteries can be used as a back-up energy source in the absence of ambient energy. The control circuitry ensures efficient use of harvested energy and maintains the charge profiles required for batteries and supercapacitors while using a minimum amount of power. In this paper we also demonstrate the feasibility of a solar and a vibrational energy harvesting microPowerChip.

Keywords: Microsystems, Power supply, microbatteries, micro-supercapacitors, energy harvesting.
