Energy harvesting based on cantilever beam for different piezoelectric materials from acoustic vibration by simulation process

This paper includes the output of a cantilever beam based piezoelectric energy harvester for various piezoelectric materials including Lead zirconate titanate (PZT), Potassium niobate (KNbO

) and poly(vinylidenefluoride-co-trifluoroethylene) (PVDF-TrFE) through some simulation process using numerous characteristics of the materials like as dielectric constant, coupling coefficient, Young modulus etc. in different excitation frequencies. The effect of the physical parameter likes piezoelectric layer length, thickness and width on voltage generation from acoustic vibration of the beam is also described in some simulated figure. The maximum output voltage is found over 7 V for KNbO
