Hi,

an electronics designer needs physical requirements.
Thus you first need to find out
* frequency (range)
* an estimation about the required power (or loudnes)
* modulated somehow? if yes, how?

Please do internet research on your own.

You also should tell us how you want it to be powered.

There are safety concerns as well -

Guidelines for the Safe Use of Ultrasound: Part II - Industrial & Commercial Applications - Safety Code 24 - Canada.ca

1991 Health Canada safety code

www.canada.ca

Above Canadian standards, visit OSHA and FDA web sites for more definitive info
if you are in USA.


Regards, Dana.
