The piezoelectric bimorph is composed of piezoelectric ceramic layers and internal electrodes co-fired together, allowing independent control of the drive voltage for each ceramic layer. Standard drive voltages include 0 - 24 and 0 - 150, and they meet the requirements for low frequency, medium - frequency, and high - frequency applications.
