A multi-modal vibration energy harvester has been developed for use on a helicopter transmission. The harvester is based on a topology optimised spring-steel cantilever-beam, with a pair of [011] poled Mn-PMN-PZT relaxor ferroelectric single crystal

This paper describes a new magnet-based method for applying a compressive pre-load to the piezoceramic elements of a Tonpilz-type acoustic projector, with the advantage of lower damping due to mechanical friction and a greater range of unhampered res

Topology optimisation has been used to design a piezoelectric energy harvester capable of harvesting the vibration present on a helicopter gearbox. The gearbox vibrations, with frequencies in the kilo-hertz range and having amplitudes of 10-100g (whe

The aim of this work is to explore a topology optimisation approach for the design of high frequency vibration energy harvesting devices capable of operating in the range of 1800–2600 Hz. The main objective of the approach is to develop an optimisa
