Abstract. 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.
