Patent ID: 7652488

Claim:
A method for nondestructively remotely measuring the health of an energetic material, comprising: embedding at least one piezoelectric capacitance sensor in the energetic material, wherein a capacitance of said at least one piezoelectric capacitance sensor is a function of a modulus of the energetic material; periodically measuring the capacitance of said at least one piezoelectric capacitance sensor; converting the measurement of the capacitance into a digital representation; communicating the digital representation through an active RFID tag to a remote communication device; relating the digital representation to the modulus; and correlating the modulus to health of the energetic material, wherein said active RFID tag includes a radio-frequency optical output and optical input, said optical input in optical and power communication through an optical fiber to an optical voltage converter in communication with a micro-controller and digital to optical converter, which is in communication with a interrogator.
