This paper presents the study of a two-degree-of-freedom (2DoF) stacked piezoelectric energy harvester (SPEH). The high performance of the 2DoF SPEH is achieved by the frequency up-conversion mechanism, which is realized by introducing a mechanical limiter. A theoretical model of the 2DoF SPEH is de...
