Method and system for sensing differential pressure with elastomer

A method for detecting differential pressure, comprising:

• placing a plurality of elastomer plates in a particular distance within a tube and sealing a particular volume of gas between said plurality of elastomer plates, wherein said plurality of elastomer plates is covered with a compliant electrode and wherein said tube is capable of connection to a flow system in order to detect a pressure difference between a plurality of detection areas;
• detecting a change in a resistance and a capacitance associated with said plurality of elastomer plates and said compliant electrode when said plurality of elastomer plates deform with respect to a change in pressure between said plurality of detection areas;
• monitoring said pressure difference between said plurality of detection areas utilizing said change in said resistance and said capacitance associated with said plurality of elastomer plates and said compliant electrode;
• and
• embedding a plurality of electrical contacts in walls of said tube that connect to said compliant electrode, wherein said compliant electrode is associated with said plurality of elastomer plates and a plurality of external circuits.
