In this work, a theoretical investigation on the energy harvesting is undertaken using one of potential smart materials; piezoelectric material. The energy equations fur both square and circular types of the piezoelectric material are derived, and the energy generated from two commercially available Products: $PZT (Lead/Zirconium/Titanium: Pb(Zr,\;Ti)O_3)$ and PVDF (polyvinylidene fluoride) are investigated in terms of the thickness and area. In addition, a finite element analysis (FEA) is undertaken to obtain the generated energy due to the uniform pressure applied on the surface of the piezoelectric materials. A comparative work between the theory and the FEA is made followed by the brief discussion on the usage of the harvested energy for Bio MEMS.
