Abstract

An electrical wetness sensor powered by the electrogalvanic action of an anode, a cathode and an electrolyte. In the preferred embodiment the electrolyte is urine and the device is used to warn of incontinence. This device contains the following features: sensitivity to wetness; electrical battery-less operation; hermetic and permanent sealing; no-maintenance operation; portability, inexpensiveness, and disposableness. The alarm unit may be configured to produce a visual and/or audible signal. In the preferred embodiment the alarm unit transmits a signal to a remote FM radio receiver or dedicated device to announce incontinence. Incontinence is announced by a tone, visual signal, silencing of the radio station the receiver is tuned to, or activation of a microphone within the alarm unit to allow remote listening. Any or all of these indications may be designed into the device and are discussed.
