A Compact, Wireless, Self-Powered Pushbutton Controller
We describe a compact piezoelectric pushbutton and associated minimal circuitry that is able to wirelessly transmit a digital ID code to the immediate region (e.g., 50–100 foot radius) upon a single button push, without the need of batteries or other energy sources. Such devices have the potential of enabling controls and interfaces to be introduced into interactive environments without requiring any wiring, optical/acoustic lines of sight, or batteries.
