Abstract
Energy harvesting is a conducive approach that assists to create sustainable and eco-friendly environment. A piezoelectric tile is capable of harvesting vibrational energy from footsteps. A lumped parameter model is introduced for the piezoelectric energy harvesting tile (PEHT) by using PZT-PZNM ceramic with stainless steel (SUS-304) substrate. A study on the dependency of tip mass, capacitance, load resistance, frequency, and electrically induced damping coefficient on voltage and generated power is conducted to analyze the behavior of the PEHT. The effect of materials on piezoelectric performance is also studied by the use of different ferroelectric relaxors and ceramics including 0.955Pb(Zn1/3Nb2/3)03–0.045PbTi03 (PZN-0.045 PT), 0.70Pb(Mg1/3Nb2/3)O3–0.30PbTiO3(PMN-0.3 PT), piezoelectric ceramics from Rostov-on-Don (Russia) (PCR-7) and Pb[Zr x Ti1–x ] O3 (PZT-5). An increment of 754% and 317% was observed in PZN-0.045 PT and PMN-0.3 PT in power while voltage increased by 192% and 104% respectively as compared to PZT-PZNM material.
