Abstract
An over torque detection system includes a mechanical torque sensor and a radio frequency identification (RFID) tag. The mechanical torque sensor includes first and second contact elements and a moveable element coupled to the first contact element. In a normal operational state the moveable element is in contact with the second contact element and creates an electrical pathway between the first and second contact elements and when in over torque operational state the movable element moves such that it does not contact the second contact element. The RFID tag is connected to the first contact element and the second contact element such that when the mechanical torque sensor is in the normal operation state the RFID tag does not transmit information, and when the mechanical torque sensor is in the over torque operation state the RFID tag does transmit information.
