Abstract

A wheel, particularly for a vehicle, includes at least a portion formed from non-metallic material which incorporates at least one sensor indicative of a condition sensed. A wheel is molded from a fiber reinforced plastics material and incorporates passive sensors capable of indicating conditions of the wheel or the tire associated with it (e.g., tire pressure or torque transmitted). The sensor output is processed by an ASIC device to provide an output signal to a communications device also mounted on the wheel. The ASIC and communications device are powered by a virtual battery which is charged by, e.g., using electrical pulses generated by strain within the wheel itself. An id tag may be provided to identify the wheel in question.
