摘要：

The electric impedance of a thin piezoelectric disc can be simulated by using two one-dimensional models. The validity of such models is verified here by comparing the theoretical and experimental electrical impedances obtained when the ceramic is placed in different viscoelastic media. It is then shown that the electric impedance of such an element, depends on the viscoelastic properties of the outside medium. An original tool for monitoring the curing and ageing of polymeric structure is then determined.
