Claim 33:
34. A self-sensing valve assembly, comprising:
a valve assembly movable from an open position to a closed position, comprising a seal having elastomeric properties, a door configured for covering an opening in a process chamber, and a valve for operating the door from the open position to the closed position, wherein the seal is seated within the valve assembly and is in contact with a surface the door of the valve assembly, wherein in operation of the valve assembly, the seal is under pressure and is subject to degradation; and
at least one sensor for measuring micro strain on an exterior surface of the valve assembly or within the valve assembly, and at least one sensor for measuring at least one other property related to a condition selected from an ambient condition of operation and a condition related to degradation of the seal in operation, wherein the sensor is in communication with a circuit capable of sending a signal from a change in voltage.
