Abstract:

A force-sensitive presence detection system, detector, and detection method are provided. The detector includes a substantially flat water-proof enclosure, having disposed therein an electrically isolating layer disposed between first and second conductive layers, wherein the electrically isolating layer has a plurality of contact regions formed therein to enable the first and second conductive layers to electrically couple in response to an application of a force thereto. A signaling device is configured to output a time-based signal to a receiver when the first and second conductive layers electrically couple. A method of detecting a body using the detector is also provided.
