Lett. 93, 224102 (2008); http://dx.doi.org/10.1063/1.30400110003-6951http://hdl.handle.net/10919/47402This letter investigates the power generation and shunt damping performance of the single crystal piezoelectric ceramic lead magnesium niobate-lead zirconate titanate (PMN-PZT) analytically and experimentally. PMN-PZT is a recently developed interface for energy harvesting and shunt damping with its large piezoelectric constant (-2252 pm/V) and coupling coefficient (0.95) for the transverse piezoelectric mode. A unimorph PMN-PZT cantilever with an aluminum substrate is tested under base excitation and its electromechanical response is predicted with a coupled distributed parameter model. The power generation performance of the device is 138 mu W/(g(2) cm(3)) at 1744 Hz, causing 84% tip vibration attenuation due to the resistive shunt damping effect.en-USIn CopyrightLead compoundsPiezoceramicsPiezoelectric transducersPiezoelectricityDielectricsArticle - Refereedhttp://scitation.aip.org/content/aip/journal/apl/93/22/10.1063/1.3040011https://doi.org/10.1063/1.3040011
