Abstract

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 electrolytes.

Claims

1. An electrolyte sensor comprising:

1. A positive trace electrode or electrodes comprised of conductive elastomer or conductive polymer whereby said electrode or electrodes are employed in a sensor pattern.

2. A negative trace electrode or electrodes comprised of conductive elastomer or conductive polymer whereby said electrode or electrodes are employed in a sensor pattern.

3. A gap or channel separating the positive electrode or electrodes of claim 1 from the negative electrode or electrodes of claim 2 whereby;

said gap or channel is of sufficient dimension to prevent an electric current from being established between the positive electrode or electrodes of claim 1 and the negative electrode or electrodes of claim 2;

said gap or channel may be used in a plurality between the positive electrode or electrodes of claim 1 from the negative electrode or electrodes of claim 2 to prevent said electric current from being established;

said gap or channel may of uneven dimension;

said gap or channel may be employed in the sensor pattern of claim 1 and claim 2 in order to separate island type electrodes;

said gap or channel being of sufficient size or sizes to allow the measuring of electrical resistance of any solid, liquid or gas or combination thereof across said gap or channel;

said gap or channel being of sufficient size or sizes to allow an electrolyte or electrolytes present in a solid, liquid or gas or any combination thereof to conduct electricity or carry an electric charge or carry an electric current between the positive electrode or electrodes of claim 1 and the negative electrode or electrodes of claim 2;

said gap or channel being utilized between the positive electrode or electrodes of claim 1 and the negative electrode or electrodes of claim 2 to form a trace pattern with said electrode or electrodes;

said gap or channel is comprised of a solid, liquid or gas or a combination thereof; and

said gap or channel is established by a means for separating the positive electrode or electrodes of claim 1 from the negative electrode or electrodes of claim 2.

4. The separating means of claim 3 including but not limited to;

attaching the positive electrode or electrodes of claims 1 and 3 and the negative electrode or electrodes of claims 2 and 3 at a distance from each other by attachment means to a flexible non conductive base portion whereby said gap or channel is established between said positive electrode or electrodes and said negative electrode or electrodes; and

employing small non conductive bridges between the positive electrode or electrodes of claims 1 and 3 and the negative electrode or electrodes of claims 2 and 3 of sufficient plurality and of sufficient rigidity to maintain said gap or channel.

5. The attachment means of claim 4 including but not limited to;

heat molding and vulcanization; and

appropriate adhesives.
