Analyses of Power Output of Piezoelectric Energy-Harvesting Devices Directly Connected to a Load Resistor Using a Coupled Piezoelectric-Circuit Finite Element Method

Zhu, Meiling; Worthington, Emma; Njuguna, James A. K. (IEEE Institute of Electrical and Electronics, 2009-07-31)

A coupled piezoelectric-circuit finite element model (CPC-FEM) is proposed for the first time to study the power output of a vibration-based piezoelectric vibration-based piezoelectric energy harvesting devices (EHDs) ...
Coupled piezoelectric-circuit FEA to study influence of a resistive load on power output of piezoelectric energy devices

Zhu, Meiling; Worthington, Emma; Njuguna, James A. K. (2012-08-01)

This paper presents, for the first time, a coupled piezoelectric-circuit finite element model (CPC-FEM) to analyze the power output of vibration-based piezoelectric energy harvesting devices (EHDs) when connected to a ...
Design and testing of piezoelectric energy harvesting devices for generation of higher electric power for wireless sensor networks

Zhu, Meiling; Worthington, Emma (2009-10-01)

This paper reports our design and testing results on the electric output performance of a vibration-based piezoelectric energy harvesting device (PEHD). The PEHD is a cantilever with a sandwich structure and seismic mass ...
Piezoelectric Energy Harvesting: Enhancing Power Output by Device Optimisation and Circuit Techniques

Worthington, Emma (Cranfield University, 2010-03-31)

Energy harvesting; that is, harvesting small amounts of energy from environmental sources such as solar, air flow or vibrations using small-scale (≈1cm 3 ) devices, offers the prospect of powering portable electronic ...
