The present invention relates to a self-generating tire, including: a controller including a generation portion for generating electricity, a power storage portion for storing the generated electricity, a sensor portion supplied with the electricity from the power storage portion so as to be operated, and a transmission module for controlling the supply of the electricity generated by the power generation portion and transmitting sensor signals collected from the sensor portion to a controller inside a vehicle. The power generation portion includes a piezoelectric sensor in a form of a film made of a natural crystal or an artificial crystal material using a piezoelectric effect. The piezoelectric sensor is inserted and molded by being connected and attached from an end portion of a bead filler, inserted into a side wall portion of a tire of the vehicle, to a shoulder portion so as to be able to induce electricity to be generated by a mechanical vibration of the piezoelectric sensor due to bending and stretching motion that is generated in accordance with driving of the vehicle. 본 발명은 자기 발전 타이어에 관한 것으로서, 전기 생성을 위한 발전부, 상기 생성된 전기를 저장하기 위한 축전부, 상기 축전부로부터 전기를 공급받아 동작하는 센서부, 및 상기 발전부에서 생성된 전기의 공급을 제어하고, 상기 센서부로부터 수집된 센서신호들을 차량 내부의 제어부로 송신하기 위한 송신 모듈을 포함하는 제어부를 구비하고, 상기 발전부는 압전효과를 이용하는 천연결정 또는 인공결정 재료로 된 필름 형태의 압전센서를 포함하고, 상기 압전센서는 차량의 타이어의 사이드월부에 삽입되는 비드필러 끝단부로부터 숄더부까지 길게 이어붙여 삽입 성형되어 차량의 주행에 따라 발생하는 굴신운동에 의해 상기 압전센서의 기계적 진동으로 전기 발생을 유도할 수 있다.
