<p>An improved urinating indicator (10) of simple construction which operates efficiently and which may be constructed much more simply than the prior art. The present invention employs two electrodes (18) spaced apart, which protrude from a sealed transparent housing (12). The electrodes (18) are connected to a power source (20) and an indicator device (14), such as a light and/or buzzer. If a stream of urine is directed onto the outer surface of the housing (12) between the electrodes (18), the urine acts as an electrolyte between the electrodes (18), thereby forming a closed electrical circuit and causing the indicator device (14) to flash and/or buzz. One or both electrodes (18) are constructed of dissimilar metals, i.e., metals which have different electromotive potential and which therefore create an electromotive force therebetween. This electromotive force is strong enough to overcome any non-conductive corrosive build-up at either of the electrodes (18).</p> |
