This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. The plies and/or the treads and/or other surfaces of the tire include one or more resonators that respond to being interrogated by an externally generated excitation signal. Multiple resonators formed of electrically-conducting materials are disposed (e.g., printed) on the plies and/or tread and/or other surfaces of the tire. Each of a group of multiple resonators can be individually configured to respond to different frequencies of the excitation signal such that the presence of a response (e.g., a measured attenuation of the excitation signal return) or lack of response (e.g., based on comparison of the excitation signal return to calibration curves) from individual ones of the multiple resonators can be combined to form a serial number that is unique to the tire or other elastomer-containing component (e.g., belts, hoses, etc.) being interrogated.

Tires including a bodies formed of one or more tire plies are disclosed. In various implementations, a tire may include several split-ring resonators (SRRs), each associated with a natural resonance frequency configured to shift in response to a change in an elastomeric property of a respective one or more tire plies. The elastomeric property may include one or more of a reversible deformation, stress, or strain. In some implementations, the one or more SRRs may include a first split-ring resonator (SRR) including first carbon particles that may uniquely resonate in response to an electromagnetic ping based at least in part on a concentration level of the first carbon particles within the first SRR and a second SRR including second carbon particles that may uniquely resonate in response to the electromagnetic ping based at least in part on a concentration level of the second carbon particles within the second SRR.

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.
