Abstract
A sensor system for obtaining data from an air spring having elastomeric body with a plurality of wireless sensors embedded therein. The sensor length-scales range from nano- to micro-scale devices that are small enough to avoid becoming occlusions within the elastomeric body. The air spring may include a spring wall having an internally reinforced elastomeric body portion with the sensors embedded within. The air spring may include a spring wall having an unreinforced elastomeric body portion with the sensors embedded within. 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 air spring.
