Abstract: A method for embedded failure detection includes embedding radio frequency identification (RFID) tags at varying depths within a composite material including a polymer, an epoxy or an aggregate bonded with a fluid. Each RFID tag is attached with an insulated wire loop and a sensor and configured to communicate tag identification and resistance on each insulated wire loop upon being energized by an RFID reader. The sensor may be for temperature, moisture, humidity, pressure, light, or acceleration. The RFID tags are read with an RFID reader after initial curing of the composite material for reference information. The RFID reader reads the RFID tags after a particular time period for current information. The current information is compared to the reference information. It is determined whether a change information has occurred for any of the RFID tags to detect a possible failure of the composite material.
