In this study, we developed a triboelectric nanogenerator (TENG) for intelligent tires. This TENG was attached on the inner surface of a racing cart tire. First, we evaluated the dependences of the TENG output on the environmental temperature and relative humidity to ensure that the proposed TENG can operate in a wide range of these parameters. Then, we packaged the TENGs in aluminum laminate film and mounted them on the inner side of the tire. The charged voltage and output voltage of the TENGs were evaluated on a moving belt. The output voltage signals were observed at the region of contact; the signals increased with rotational speed and load weight but decreased with tire pressure. The charged voltage in the 10 μF capacitor was found to be approximately 14 V, which corresponds to 1.0 mJ at the speed of 16 km/h after the tire rotated for 15 min. These results suggest that the proposed TENG can operate as an energy harvester for the temperature and pressure sensors built into intelligent tires.
