Paper Abstract

For the practical implementation of an energy harvesting system, the signal conditioning electronics play an important role in defining the overall efficiency of these power systems. There are currently a number of commercially available energy harvesting circuits designed to condition the output of piezoelectric-based electromechanical transducers. In this paper we present a comparison study of several of these commercially available circuits, using a collection of transducer designs to evaluate performance as a function of energy level and frequency content. This evaluation considers conditioning circuits that range from simple rectification designs to others that incorporate logic-based integrated circuits designed to optimize energy throughput. Custom circuit designs are also considered as part of this study, including switching circuits designed to allow for mult-source energy harvesting.
