Abstract
Tires including a tire bodies formed of one or more tire plies are disclosed. In some implementations, tire plies may include a temperature sensor that may detect a temperature of a respective tire ply. The temperature sensor may include a ceramic material organized as a matrix and one or more split-ring resonators (SRRs). Each of the SRRs may have a natural resonance frequency configured to shift in response to one or more of a change in an elastomeric property or a change in the temperature of a respective one or more tire plies. The temperature sensor may include an electrically-conductive layer dielectrically separated from a respective one or more SRRs. A thickness each of the SRRs may be approximately between 0.1 micrometers (μm) and 100 μm.
