Abstract:
A power-generating device includes a vibration plate, a lower electrode on the vibration plate, a piezoelectric layer made of piezoelectric material on the lower electrode, and an upper electrode on the piezoelectric layer, a fixing member for supporting a fixed end of the vibration plate. The vibration plate applies compressive stress to the piezoelectric layer when the vibration plate does not vibrate. The power generating device is excellent in long-term reliability.
