A nanogenerator is integrated onto a tire's inner surface and scavenges mechanical energy from deformation of the tire during its motion. A liquid crystal display (LCD) screen is lit directly by the nanogenerator. The possibility of scale‐up is demonstrated and the potential to use the nanogenerator a self‐powered tire pressure sensor and speed detector in mobile vehicles is shown.
