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.
