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.
