Measuring the properties of the piezoceramic samples under different thermodynamical and excitation conditions

Several piezoceramic samples have been characterized by using different thermodynamical and excitation conditions in thermal isolated oven at INETEC L.t.d. It has been observed strong coupling between thermodynamical effects induced by different temperatures (from 25 degrees up to 125 Celsius degrees)  and nonlinear effects induced by large excitation fields of piezoceramic samples.
