Provided is a piezoelectric tire in which peeling and cracking of electrodes constituting piezoelectric elements are suppressed, and durability of the piezoelectric tire is improved. A piezoelectric tire (1A) is provided with a tire main body (2), a coating-type piezoelectric part (3), and a circuit unit (4). The coating type piezoelectric part (3) is coated on the tire main body (2) and generates electric power corresponding to strain generated on the ground contact surface of the tire main body (2). The circuit unit (4) is provided in the tire main body (2) and is driven by the power generated by the coating-type piezoelectric part (3). A coating-type piezoelectric part is used as the piezoelectric part (3), and the piezoelectric part (3) is in close contact with the tire main body (2), so that peeling and cracking of electrodes constituting the piezoelectric part (3) can be suppressed. As a result, the durability of the piezoelectric tire (1A) is improved without compromising the ability to follow the strain of the tire main body (2).
提供压电轮胎,抑制构成压电元件的电极的剥离、破裂,实现作为压电轮胎的耐久性的提高。压电轮胎(1A)具有轮胎主体(2)、涂布型压电部(3)以及电路单元(4)。涂布型压电部(3)涂布于轮胎主体(2),生成与在轮胎主体(2)的接地面产生的应变对应的电力。电路单元(4)设置于轮胎主体(2),利用由涂布型压电部(3)生成的电力进行驱动。通过使用涂布型的压电部作为压电部(3),压电部(3)与轮胎主体(2)紧贴,能够抑制构成压电部(3)的电极的剥离、破裂。其结果是,不会损害对轮胎主体(2)的应变的追随性,提高了作为压电轮胎(1A)的耐久性。
