TIRE DEVICE
First Claim
1. A tire device, comprising:
- a vibration power generating element that is arranged inside a tire and outputs a voltage corresponding to a time variation of a vibration generated in a tread of the tire;
a signal processing unit that is arranged inside the tire and performs signal processing on the voltage outputted from the vibration power generating element; and
a transmitter that is arranged inside the tire and sends data, which is prepared by signal-processing the output voltage, in the signal processing unit to an external device arranged outside the tire, wherein the signal processing unit and the transmitter are driven by power generated in the vibration power generating element.

Abstract
A tire device includes a vibration power generating element, a signal processing unit, and a transmitter. The vibration power generating element is arranged inside a tire and outputs a voltage corresponding to a time variation of a vibration generated in a tread of the tire. The signal processing unit is disposed inside the tire and performs signal processing on the voltage outputted from the vibration power generating element. The transmitter is arranged inside the tire and sends data subjected to the signal processing in the signal processing unit to a device provided outside the tire. The signal processing unit and the transmitter are driven by power generated in the vibration power generating element.
