Introduction

Advanced applications of energy harvesters

Using the fundamental principles outlined before, it is possible to

apply the energy harvesting approaches to advanced problems.

This lecture will introduce four new topics to demonstrate few

advancements in the field.

Topic 4: Energy harvesting dynamic vibration absorbers

Future research directions

Huge potential for the application of classical/modern random

vibration analysis techniques

Vibration energy harvesting under non-Gaussian random

excitations - linear and nonlinear systems

Generalisation of the results to higher dimensional cases (3 or 4

dimensional state-space models)

Stability issues - energy harvesting from instability?

Vibration control - simultaneous control and energy harvesting -

extension of EHDVA - perhaps active control?

Stochastic systems + nonlinearity in higher dimensions

Hybrid piezo-electric and electro magnetic energy harvesting

Multi-scale energy harvesting - incorporating nano-scale

piezoelectric materials such as ZnO, GaN and BN nano tubes and

nano wires

Parameter optimisation
