Abstract

A tire assembly with energy harvesting capabilities includes a tire structure and an acoustic-electric transducer configured to convert acoustic energy generated upon movement of the tire structure to electrical energy. An example of an acoustic- electric transducer corresponds to a microphone including a membrane that vibrates upon subjection to sound waves, a magnet and a wire coil surrounding at least a portion of the magnet. The transducer serves to produce an electric current in the wire coil that is coupled to additional power conditioning elements such as a rectifier, an energy storage device (e.g., capacitor or rechargeable battery) and a voltage regulator. Sufficient accumulations of harvested energy can then power tire electronic systems, including various condition-responsive devices (i.e., sensors, etc.) a revolution counter, a radio frequency (RF) device, a rechargeable battery or a lighting device.
