Claim Text:
1. A method for embedded failure detection comprising: embedding a plurality of radio frequency identification (RFID) tags at varying depths within a composite material, the RFID tags are each attached with an insulated wire loop, the composite material comprises a polymer, an epoxy or an aggregate bonded with a fluid, wherein each of the plurality of RFID tags are configured to communicate tag identification and resistance on each insulated wire loop upon being energized by an RFID reader; reading, by the RFID reader, the plurality of RFID tags after initial curing of the composite material for reference information including a first resistance reading, a first position and a first location for each identified RFID tag of the plurality of RFID tags; storing the reference information; reading, by the RFID reader, the plurality of RFID tags after a particular time period for current information including a second resistance reading, a second position and a second location for each identified RFID tag of the plurality of RFID tags; storing the current information; comparing the current information to the reference information for each of the plurality of RFID tags; and determining whether a change in one or more of resistance, position and location has occurred for any of the plurality of RFID tags based on the comparing to detect a possible failure of the composite material.
