Journal ArticleDOI
Broadband piezoelectric energy harvesting devices using multiple bimorphs with different operating frequencies
TL;DR: Numerical results show that the OFB of the piezoelectric energy harvesting devices can be tailored by the connection patterns (i.e., in series and in parallel) among PBs.
Journal ArticleDOI
Performance of a piezoelectric bimorph for scavenging vibration energy
TL;DR: In this paper, the performance of a piezoelectric bimorph in the flexural mode for scavenging ambient vibration energy and evaluate the dependence of the performance upon the physical and geometrical parameters of the model bimomorph.
Journal ArticleDOI
Transmitting electric energy through a metal wall by acoustic waves using piezoelectric transducers
TL;DR: The feasibility of transmitting electric energy through a metal wall by propagating acoustic waves using piezoelectric transducers is examined by studying the efficiency of power transmission and its dependence upon the relevant system parameters for a simplified system consisting of an elastic plate sandwiched by two piez Zoelectric layers.
Journal ArticleDOI
A piezoelectric power harvester with adjustable frequency through axial preloads
Yuantai Hu,Huan Xue,Hongping Hu +2 more
TL;DR: In this article, the axial preloading of a piezoelectric bimorph vibrating in the flexural mode was studied for a power harvester to effectively scavenge energy from ambient mechanical vibrations/noise with varying frequency spectra.
Journal ArticleDOI
Exact solutions to the electromechanical quantities inside a statically-bent circular ZnO nanowire by taking into account both the piezoelectric property and the semiconducting performance: Part I--Linearized analysis
TL;DR: In this article, the effect of initial carrier concentration on both electric fields and output voltage of a bent ZnO nanowire is discussed in detail, and it is found that the semiconducting performance results in some reduction in output voltage, which comes from the partial cancellation on the piezoelectric electric fields due to carrier redistribution.
