Energy harvesting for the purpose of powering low power electronic sensor
systems has received explosive attention in the last few years. A common
device uses the piezoelectric effect for a cantilever beams at resonance to
harvest ambient vibration energy. However most of these devices have a
rectangular piezoelectric patch covering all or part of the beam. This paper
considers the optimum design of such a device, and in particular investigates
the effect that the size and shape of piezoelectric sensor has on the harvested
energy. It is shown that significant increases in harvested energy may be
obtained by optimising the sensor design.
