An electrolyte sensor that uses conductive elastomer electrodes. Examples of the intended analytes for sensor use include those found in urine, saliva, blood, feces and spinal fluid, although other analytes exist for electrolyte detection. Conductive elastomer trace electrodes are separated by a gap or channel which can be bridged by an electrolyte and thereby complete an electrical circuit to an alarm or other circuitry. Gap or channel distances vary the level of electrical resistance associated with detecting certain analytes.
