Hi,
I'm working on a sonoluminescence project for the science fair.I'm just trying to get the setup to work, and get a bubble to glow. To get it to work, I need 3 Piezoceramic transducers (2 drivers, 1 microphone). Does anyone know where I can get these type of transducers, and what type they need to be? Basically, I'm asking if anyone knows where piezo transducers that would work in a sonoluminesence experiment might be bought.

~And, for futher clarification, the transducers don't need to be waterproof because they are outside the flask.

Aren't these the same as ultrasonic transducers? I recall an experiment that used high power ultrasonic transducers to illuminate a suspended bubble in water. Perhaps the transducers resonate the bubble and the microphone feds back to some sort of controller?

Ebay or www.steminc.com may be a source for something like this, but I doubt if you can easily find something as powerful.

Or look for barium titanate transducers.
