A system may include a fastener having a trench formed in a side of a head of the fastener. The system may further include a magneto-elastic component spanning the trench and attached to the head of the fastener on both sides of the trench. The system may also include a coil wrapped around the magneto-elastic component between both sides of the trench. The system may include a radio frequency identification (RFID) circuit, where the coil may be electrically connected to the RFID circuit resulting in a resonance response frequency that is a function of a strain level applied to the magneto-elastic component.
