Specific material detection and measuring device

A capacitive detection device for sensing the presence of and measuring the concentration of a specific non-aqueous material or a complement of the specific non-aqueous material in a fluid, the device comprising:

• a capacitor having a plurality of spaced apart electrically conductive electrodes adapted to receive an electrical input and emit an electrical output to create a capacitive electric field therebetween;
• a first electrically insulative material layer covering said electrically conductive electrodes;
• and
• a second material membrane spatially located from said first material layer, said second membrane communicating with the fluid and permeable to the specific non-aqueous material whereby the specific material may be sensed and concentration measured as a consequence of its entering and leaving the electric field between said electrodes and thereby changing its capacitance between said electrodes.

A gas detection device for sensing the presence of and measuring the concentration of a specific gas in a gaseous fluid, the device comprising:

• a capacitor having a plurality of spaced apart electrically conductive electrodes, said electrodes adapted to receive an electrical input and emit an electrical output to create a capacitive electric field therebetween;
• a first electrically insulative material layer passive to the gaseous fluid covering said electrically conductive electrodes;
• and
• a second material layer covering said first material layer, said second material layer being selectively permeable to the specific gas in the gaseous fluid whereby the specific gas may be sensed and its concentration measured as a consequence of its entering the electric field between said electrodes and thereby changing the capacitance between said electrodes.
