ABSTRACT:
A pressure sensor includes a housing portion with a fluid inlet and a polymer element within the housing portion. The polymer element may be coated with piezoresistive material to form a first resistor and may have associated electrodes. The polymer element includes a first resistance value that changes to a second resistive value in a response to a predetermined condition. The pressure sensor may also include a second polymer element that includes a first resistance value that changes to a second resistive value in a response to a predetermined condition.
