Piezoelectric Single Crystal Power Generator for Low Frequency Vibrating Machines and Structures
Relaxor-based ferroelectric Pb(Zn1/3Nb2/3)O3 -(6-7)%PbTiO3 single crystal of 110L×001T(P) cut exhibits high d31 and 11 low s E values, making it candidate for piezoelectric energy harvesting. In this work, a cantilever piezoelectric power generator using this crystal cut has been designed and fabricated. The device is designed for 110 Hz of resonance. The peak voltage generated from the prototype device at resonance is ≈ 40 V/g, g being the acceleration due to gravitation. The maximum power harvested is about 1 mW/g, which increases with the square of the acceleration. Both analytical and experimental results of the device are presented and discussed.
