Hello everyone,
I am completely new in this field so my apologies in advance if I make elementary questions:
My project summary: I need to use the reverse piezoelectric effect and make a piezoelectric motor drive to create vibrations. The piezo element is going to attach the external wall of beaker (liquid container) and creates vibrations with a push button to produce ULTRASONIC (> 80 kHz in my case) vibrations and detaches micron size bubbles that are attached to the beaker wall. I have found manufacturers who can provide me with tiny (2*2*2 mm) piezos but suggest me to use an amplifier.
And here are my questions:
1) Why do I need an amplifier to amplify the output from my ac power?
2) What are the main components I need to make this kit and attach it to the walls of the liquid container?
Thank you so much and sorry for my limited knowledge and probably naive questions.
