... "The microsensor circuit contains a thermal fuse, a radio-frequency identification (RFID) microchip, a capacitor, and a coil antenna. The purpose of this microsensor is to indicate the occurrence of excessive temperature at the bond-line between the TPS and the structure of an RLV. The fuse opens at about 288oC, the multiple-use temperature limit of RTV-560, which is a common TPS bonding agent. The rest of the circuit is designed to return the microchip identification code, and a signal for whether or not the fuse is open, to a wireless radio-frequency transceiver" ...
