ABSTRACT:
The invention encompasses a living organism sensing device. Such device comprises a conductive loop extending over a substrate. The loop comprises carbon particles. The device further comprises a circuit which includes the conductive loop as a first circuit component and a transponder as a second circuit component. The transponder is configured to emit a first signal if the loop of conductive material is continuous and a second signal if the loop of conductive material is broken. The second signal is different than the first signal. The invention also encompasses a termite sensing device. Such device includes at least one wooden block, and a conductive loop proximate the wooden block. The loop comprises conductive particles of carbon. The termite sensing device further includes an electrical circuit comprising the conductive loop as a first circuit component and a transponder as a second circuit component. The transponder is configured to emit a first signal if the conductive loop is continuous and a second signal if the loop is broken. The second signal is different than the first signal.
