Do you know piezo driver modules?

I didn’t know the piezo driver modules before. Until I was involved in a project on piezo driver modules.
Piezo driver modules are designed to drive large piezos at high speed and high efficiently. They have a built-in waveform generator that generates sinusoidal waves, square waves, and triangular waves. The changes of these waveforms are used to control the way and trajectory of cloud shareholders in piezos.
