I have several piezoelectric stacks that I am trying to get to shake/oscillate. An example of what I mean by piezoelectric stack is something like Thorlabs PA3CEW.
The drive voltage is specified as 0 - 100 V. I am wondering, in order to create the best-designed "shaker", should one drive the piezo with either:
- Square wave moving between 0 Vdc and 100 Vdc
- Square wave moving between -100 Vdc and 100 Vdc
- AC sine wave of 100 Vrms
Thank you in advance for your guidance! I am new to working with piezoelectric devices.
