    This would be neat for a bunch of passive IoT buttons. No need for a piezo to generate power, good for a couple presses at a time, just simple stuff like that.

      Charge up a capacitor and allow a single button press to send a radio signal. Or maybe have enough power to send a WiFi signal.

      I wonder if it could power a sensor. Something like a soil dampness or thermometer, where you only need a few updates per day. Could be pretty cool for passive monitoring applications.
