Description Relaxor-based ferroelectric Pb(Zn(1/3)Nb(2/3))O(3) -(6-7)%PbTiO(3) single crystal of [110](L)x[001](T)(P) cut exhibits high d(31) and low S(11)(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 approximate to 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.
