 When I hear the word piezo, I think of a little fragile disc that can convert mechanical pressure into a small electrical charge. Which is cool, piezodisks are amazing. But I was not aware piezo electric material could be made into a thin and flexible film. But this two-foot piezo ribbon sensor has enlightened me. So what do you do with a flowing silver strip that senses mechanical stress? Well, I'm sure there's some impressive biohacking project would be great for, but get this, electronic wind chime. The wind blows, bends the ribbon, which creates a charge sensed by the itsibiti board, which in turn passes electricity to a, you guessed it, piezo buzzer. Which plays a lovely chime. Yeah, we're gonna have to work on the chime.
