Abstract: A bimorph actuator can maintain a piezoelectric constant if it uses thin piezoelectric film. The bimorph actuator comprises a vibrator (18) defining its surrounding and a piezoelectric film (19) formed on the vibrator (18) and bent in the middle. Even a thin piezoelectric film can achieve a desired piezoelectric constant suitable for low-voltage driving since the piezoelectric film (18) releases residual stresses.
