Abstract

To increase the efficiency of vibration-based energy harvesting, nonlinear piezoelectronic energy harvesting wired in parallel is proposed in this paper. With the results from simulation of two, three parallel energy harvesting, it is demonstrated that parallel nonlinear piezoelectric energy harvesting can generate more power output and there is an interval of frequency over which the curve of efficiency is smooth and the motion of the harvester is periodic. This interval is defined as effective working band in this paper. The width of effective working band varies with the variation of the difference between the lumped parameters for each harvesting, and will be the widest only when the lumped parameters of each harvesting are equal respectively.
