Abstract
Systems for detection of tire strain in a vehicle are disclosed. In some implementations, the system may include an antennae disposed on one or more of the vehicle or a vehicle component and may output an electromagnetic ping. The system may include a tire with a body formed of one or more tire plies. Any one or more of the tire plies may include split-ring resonators (SRRs). Each SRR may have a natural resonance frequency that may proportionately shift in response to a change in an elastomeric property of a respective one or more tire plies, the elastomeric property including one or more of a reversible deformation, stress, or strain. The SRRs may include SRR with carbon particles that may uniquely resonate in response to an electromagnetic ping based at least in part on a concentration level of the carbon particles within the SRR.
