  • System and method for tracking torsion of a screw
    Patent number: 11903625
    Abstract: A system for determining the torsion of a screw is provided. The system generally comprises a first washer, second washer, spring, radio frequency identification (RFID) tag, and interrogation device. A screw is inserted through the system and provides the compression force necessary to bring the first washer and second washer separated by the spring in contact with one another, thus creating a complete circuit from the first circuit portion and second circuit portion of the signal transmitter. The interrogation device is used to send and receive information to and from the signal transmitter. An encasing may be used to encapsulate the first washer, second washer, spring, and signal transmitter in a way such that they are protected from the environment.
