Abstract
A tire system includes a plurality of piezoelectric devices mounted to the tire. The piezoelectric devices provide output signals in response to deformation of the tire. A processor has input terminals for receiving the signals from the piezoelectric devices, and the processor is programmed to determine tire parameters in response to the output signals from the piezoelectric devices. A power converter has input terminals for receiving the signals from the piezoelectric devices, and the power converter is connected to the processor to power the processor.
