Abstract

This paper studies the method of increasing output power of multilayer piezoelectric energy harvesters using Single Supply Pre-biasing (SSPB). In SSPB, it is important that the pre-biasing voltage be applied at the right moment. Multilayer piezoelectric energy harvesters are well suited SSPB as there is no phase lag between piezoelectric charge displacement on each layer and one layer can therefore be used for switch timing control. Compared to previously reported SSPB circuits, the power consumption of the circuit has been significantly reduced. Experimentally, the output power of a bimorph single-layer energy harvester using SSPB has been increased by a factor of three compared to that using a bridge rectifier. Furthermore, the possibility of implementing SSPB in bimorph double-layer energy harvesters has also been investigated.
