NOVELTY - A tire assembly comprises a tire structure, a piezoelectric device for generating electric charge in the tire structure which is subjected to mechanical strains; an energy storage device coupled to the piezoelectric device for receiving and storing the electric charge and an electronics assembly coupled to the storage device so that selected electronic components are powered by the electric charge.    USE - As self-powered tire electronic system for generating electric power from a rotating tire's mechanical energy; and provides measurement capabilities, monitoring and warning system, vehicle feed back system, and asset tracking potential for commercial truck fleets, airplanes and mining/earthmover equipment.    ADVANTAGE - The stored energy is used to power electronics such as a tire monitoring system that wirelessly transmits such information as tire pressure, temperature and identification variables to a remote receiver location. Sufficient accumulations of the stored energy can power electronic systems including components for identifying various physical tire parameters as well as radio frequency (RF) transmission devices. The tire monitoring system reduces the amount of required signal hardware relative to conventional tire monitoring systems. By providing a tire monitoring system that is self-powered, no scavenger antennas or multiple receiver locations with additional hardwire connections are required. There are fewer limitations regarding the type and amount of electronic equipment capable of utilization within tire and wheel assembly structures.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronics assembly for integration with a predetermined physical environment.
