Piezoelectric disks/pads - tap to generate a voltage pulse! (Kit of 12)
Originally made as a guitar sound pickup device. However, these pads can be used as an instructional tool for how piezoelectric materials can be used to harvest energy. A short, quick tap will generate a voltage pulse that is typically enough to flash a small LED in a dark room. You can easily pick up the voltage measurement on our multimeter. Use with the Piezoelectric lesson plans from The American Ceramic Society on our Outreach Resources page.
