Tire having wireless micro and nano sensors
First Claim
1. A pneumatic tire comprising:
- a pair of bead rings;
a body cord ply extending between the bead rings;
an innerliner disposed inwardly of the body cord ply;
a belt layer disposed outwardly of the body cord ply;
a pair of sidewalls disposed outwardly of the body cord ply; and
a sensor layer including a plurality of micro-scale sized or smaller sensors each providing wireless signal data related to one or more physical properties of the tire.

Abstract
A sensor system for obtaining data from an elastomeric article includes at least one wireless sensor. The sensor length-scales range from nano- to micro-scale devices that are small enough to avoid becoming occlusions within the article. The article may include sensors embedded within one of the materials of the article, a layer of sensors built into the article, and a string of sensors disposed within a component or embedded within a component of the article. The sensors may be configured to provide data related to one or more of temperature, pressure, sidewall flex, stress, strain and other parameters. The sensors may be LCD sensors, and/or conductive polymer sensors, and/or bio-polymer sensors and/or polymer diodes suitable for sensing data during the operation of the tire. A power circuit using energy generated by the tire may provide power to the sensors.

13. A pneumatic tire comprising:
-
a pair of bead rings; a body cord ply extending between the bead rings, the body cord ply having a plurality of body cords encased in a body cord ply material; an innerliner disposed inwardly of the body cord ply; a belt layer disposed outwardly of the body cord ply;
the belt layer having a plurality of cords encased in a belt layer material;a pair of sidewalls disposed outwardly of the body cord ply;
the sidewalls being fabricated from a sidewall material; anda plurality of micro-scale sized or smaller sensors providing wireless signals providing data related to at least one physical property of the tire, the sensors embedded in at least one of the body cord ply material, the belt layer material, and the sidewall material, each sensor having a size similar to carbon black or smaller thereby being sufficiently small enough to avoid being an occlusion. - View Dependent Claims (14, 15, 16, 17, 18, 19)
