ABSTRACT:
A thumb-sucking alarm system includes a pair of spaced-apart sensor electrodes carried on a moisture-accepting portion of a flexible sensor tape adapted to be wrapped around the user's thumb, the electrodes being respectively connected to conductive lead strips on an elongated coupling portion of the tape, the distal end of which is wrapped around a plug for insertion into a mating receptacle in a housing adapted to be secured by a strap around the user's wrist. The conductive strips contact terminals of a battery-powered transistorized alarm circuit in the housing which generates an audible alarm signal in response to establishment of an electrical path between the electrodes by the moisture in a user's mouth when he sucks his thumb. A test button is provided on the housing for testing the audible signal generating circuit.
