摘要:
A sensor or actuator includes a piezoelectric thin film device including a lower electrode, a piezoelectric thin film and an upper electrode, and a voltage detecting device connected between the lower and upper electrodes of the piezoelectric thin film device. The piezoelectric thin film is formed of an alkali niobium oxide-based perovskite material expressed by (K1-xNax)NbO3 (0
