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.

Differential Voltage Control
Three - wire drive, capable of bending upwards or downwards. The positive wire is connected to 150V, the negative wire to 0V, and the middle electrode is controlled between 0 - 150V. When the voltage is between 75 - 150V, it bends upwards, when the voltage is between 0~ - 75V, it bends downwards.
Single - Side Control
Two - wire drive, bending only in one direction. The negative wire is connected to 0V, and the middle electrode is also connected to 0V. The positive wire is connected to 150V, resulting in upward bending.
