Radioisotopic battery and capacitor system for powering Wireless Sensor Networks

摘要

A power source consisting of an indirect conversion radioisotopic battery and a capacitor is developed in order to power a Wireless Sensor Network (WSN) sensor node. Design, fabrication and testing of this power source is undertaken and reported upon. The storage capacitor was charged at a maximum determined power of 575 nW by the radioisotopic battery. The power cycle requirements of a WSN sensor node are examined and separated into clearly delineated segments. The power source under examination may be suitable to provide all or only some of the segments of power required by a WSN sensor node.
