...Zehao Wu; Qingsong Xu This paper presents the design, fabrication, and testing of a novel single stack-based piezoelectric energy harvester (PEH) for harvesting energy from three-degree-of-freedom (3-DOF) force excitation. One uniqueness lies in that the 3-DOF energy harvesting is implemented...

...D. Castagnetti Energy harvesting devices capable of converting freely-available ambient energy into electrical energy have received significant attention recently. Ambient kinetic energy is particularly attractive for conversion since it is almost ubiquitous and easily accessible. Piezoelectric...

...H. J. Song; Y. T. Choi; G. Wang; N. M. Wereley This study investigates the performance of an energy harvester (EH) utilizing a single crystal lead magnesium niobate-lead titanate (PMN-PT) material via analysis and experiment. The EH, intended to convert mechanical energy at a harmonic frequency...

...Longhan Xie; Carmen G. Menet; Ho Ching; Ruxu Du Invented more than 200 years ago, the automatic winding device of mechanical watch movement is one of the most successful energy harvesting devices. It harvests the kinematical energy from body movements and drives the mechanical watch movement...
