摘要

There are a number of approaches to power harvesting that are under-exploited in many applications germane to sensing and communication. Power can usually be obtained from numerous sources - such as solar, thermal, vibrational, and electromagnetic energy - using a variety of transduction methods. However, in general a power harvesting system and its associated electronics interface are designed only to exploit a single energy source. This research presents the development of innovative ways of gathering power and addressing the design issues in providing a unified energy source from disparate power harvesting approaches, specifically alternating and direct current methods. These power sources are integrated into a single source to be utilized for sensing and communication. Several circuit designs are offered to improve the combined energy harvesting performance over that of the individual harvesters. The transient dynamics of charging a storage capacitor are presented for the individual and combined power sources. Complications arising from backwards electromechanical and mutual coupling are discussed.
