Abstract

This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. In some implementations, the plies and/or the tread include a resonator that generates a resonant signal in response to being activated by locally generated power or by an externally generated excitation signal. Multiple resonators formed of carbon-containing materials are distributed in the plies and/or tread to respond to changes to the tire by altering a characteristic of the resonant signal. Such alterations include frequency shifting of the resonant signal and/or attenuation of the resonant signal. The resonator can be configured to resonate at a first frequency when a structural characteristic of a respective ply or tread is greater than a level, and to resonate at a second frequency different than the first frequency when the structural characteristic of the respective ply or tread is not greater than the level.

First claim

What is claimed is:

1. A tire comprising:
a body; and
a plurality of plies surrounding the body, at least some plies of the plurality of plies comprising a number of carbon-based microstructures distributed in one or more portions of a respective ply of the at least some plies, wherein each of the carbon-based microstructures is self-assembled, at least some of the plies are configured to resonate at one or more corresponding unique frequencies, and one or more material properties of the carbon-based microstructures are defined during synthesis of the carbon-based microstructures.

2. The tire of claim 1 , wherein one or more of the number of carbon-based microstructures comprises a plurality of three-dimensional (3D) aggregates formed of graphene sheets and coupled together to create a 3D hierarchical open porous structure.

3. The tire of claim 2 , wherein the 3D hierarchical open porous structure comprises mesoscale structuring.

4. The tire of claim 2 , wherein one or more of the number of carbon-based microstructures further comprises a porous arrangement formed in the 3D hierarchical open porous structure.

5. The tire of claim 2 , wherein the graphene sheets comprise one or more of single layer graphene (SLG), few layer graphene (FLG), or many layer graphene (MLG).

6. A tire comprising:
a body;
a plurality of plies surrounding the body, at least some plies of the plurality of plies comprising a number of carbon-based microstructures distributed in one or more portions of a respective ply of the at least some plies, wherein each ply of the at least some plies is configured to resonate at one or more corresponding unique frequencies; and
additive materials configured to modify a surface functionality of exposed surfaces of the at least some plies of the plurality of plies.

7. The tire of claim 1 , wherein the carbon-based microstructures are nucleated from a homogenous nucleation.

8. The tire of claim 1 , wherein the carbon-based microstructures are configured to be grown at least in part by a vapor flow stream.

9. The tire of claim 8 , wherein the vapor flow stream is configured to be flowed at least in part into a vicinity of a plasma.

10. The tire of claim 9 , wherein the vapor flow stream is flowed at a pressure range between a vacuum and substantially atmospheric pressure.

11. The tire of claim 1 , wherein the carbon-based microstructures are grown from a carbon-based gaseous species.

12. The tire of claim 11 , wherein the carbon-based gaseous species is configured to be controlled by gas-solid reactions under non-equilibrium conditions.

13. The tire of claim 1 , wherein one or more of the number of carbon-based microstructures is configured to resonate at a unique frequency in response to a ping from a transceiver.

14. The tire of claim 13 , wherein the transceiver is configured to interact with a tire pressure monitoring system (TPMS).

15. A tire comprising:
a body; and
a plurality of plies surrounding the body, one or more of the plurality of plies including a distribution of self-assembled carbon-based microstructures and configured to generate a respective resonate signal that resonates at one or more corresponding unique frequencies in response to an excitation signal, wherein the distribution of self-assembled carbon-based microstructures is configured to attenuate the resonant signals generated by the one or more plies proportionate to an extent of wear experienced by the tire.

16. The tire of claim 15 , wherein an amplitude of a respective one of the attenuated resonant signals is indicative of the extent of wear.

17. A tire comprising:
a body;
a plurality of plies surrounding the body; and
a plurality of carbon-based microstructures distributed in one or more of the plurality of plies, wherein each of the one or more plies is configured to resonate at one or more corresponding unique frequencies, at least one of the plurality of carbon-based microstructures is configured to resonate at a known signature frequency or frequencies, and a thickness of the one or more plies is configured to at least partially attenuate an amplitude of the known signature frequency of frequencies.

18. The tire of claim 17 , wherein one or more plies of the plurality of plies is configured to resonate at a frequency shifted away from the known signature frequency or frequencies based on changes in a dielectric constant.
