While we normally see piezo elements being used to output audio, [Veedo] thought that they could be used in a more useful manner. He bought way too many piezo film tabs and decided to use them to b… ...

It’s an electronic device commonly used to produce and signaling a procces that is happening through a sound, beep or etc. The Piezo buzzer produces sound through electricity. Some uses of Piezo ...

A piezo element captures the vibrations and abrasions between the gears, amplifying and blending them with the sculpture’s natural acoustic soundscape. This creates a unique auditory experience ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.

Clearly, the little cans aren’t going to make very much sound on their own, but with a piezo speaker element used in reverse, the cans become touch sensors that feed an Arduino and drive a MIDI ...
