In this work a cantilever beam has been chosen as the element of study, consisting of a piezoelectric polymer like PVDF with a thin permalloy layer coating on one side of it. This piezoelectric cantilever is designed using COMSOL software.

It is seen that the deflection of the tip of a unimorph cantilever is dependent on its geometric dimension, type of material and the applied field. Hence in this work, a systematic investigation has been carried out to study the influence of the length, width and of the applied external field on the deflection of the cantilever. The optimization of the dimensions of the device has been found by adjusting different parameters and dimensions and will be presented.
