主 题:Vibration power scavenging partially covered piezoelectric distributed parameter electromechanical model electrical resistance impedance matching
摘 要:Among the various techniques of power scavenging,piezoelectric energy harvesting usually has more power *** piezoceramics are usually more efficient than other piezoelectric materials,since they are very brittle and fragile,researchers are looking for alternative *** Cellulose Electro-active paper(EAPap)has been recognized as a smart material with piezoelectric behavior that can be used in energy scavenging *** majority of researches in energy harvesting area,use unimorph piezoelectric cantilever *** paper presents an analytical solution based on distributed parameter model for partially covered pieoelectric cantilever energy *** purpose of the paper is to describe the changes in generated power with damping and the load resistance using analytical *** analytical data are verified using experiment on a vibrating cantilever substrate that is partially covered by EAPap *** results are very close to each *** asymptotic trends of the voltage,current and power outputs are investigated and expressions are obtained for the extreme conditions of the load *** new findings provide guidelines for identification and manipulation of effective parameters in order to achieve the efficient performance in different ambient source conditions.
