Abstract

MEMS and NEMs devices benefit many applications due to their unique performance and tiny size. We have researched replacing components of a Wireless Sensor Network (WSN) mote with several such devices. In this paper, we present an energy conversion and storage circuit that can be used with piezoelectric nanogenerators for self powered motes. Energy from external vibration or environmental acoustics is capacitively stored and released at certain time intervals according to the application. Stored and lost power is compared against a detailed WSN mote power budget to size the generator and capacitor.
