Abstract

Piezoelectric 0.72 Pb(Zr_0.47Ti_0.53)O₃-0.28 Pb[(Zn_0.45Ni_0.55)_1/3Nb_2/3]O₃ + 0.5 mol% CuO (PNNC) particles were made for use in a composite of flexible energy harvester (FEH) that can convert sustainable mechanical deformation into electrical energy. The PNNC particles with a high transduction coefficient (d₃₃ × g₃₃) were mixed with polydimethylsiloxane (PDMS) matrix to produce the FEH. The FEH generated maximum output voltage of 55.24 V and current density of 2.76 μA/cm² (power density: 554 μW/cm³, 3.2 mW) at the resonance frequency of 11 Hz. The energy conversion efficiency of about 20.7% has been achieved. The developed energy harvester is demonstrated in the self-powered wireless sensor node application in which the FEH spontaneously generated stable power under continuous mechanical stress.
