An Ultrasonic Piezoelectric Power Generator for Public and Industrial Buildings Application

This paper presents an ultrasonic micro power generator using the piezoelectric direct effect phenomena. The consists of 2 main elements, a movement matt including PZT elements and energy harvesting circuit. is made up four each element creating cantilever beam. circuit LTC3588 Evaluation Board LDR night light. Computer simulation modelling finite analysis for proposed generation method discussed used in design development process. Finite has been to evaluate structure by performing algebraic solution set equations, describing ideal model structure, with number variables. enabled select material best operation. A prototype was built tested. demonstrated that could produce 36V, although overall impedance such devices shown be linear depending on force applied average 36M?. Energy allowed output super capacitor step charged taking time 35-minutes charge 2-minutes discharge through selected load.
