In article number 1800140 , Chi Zhang, Xinjian Li, and co‐workers develop a self‐powered Hall vehicle sensor for an automobile safety system, which integrates the triboelectric nanogenerator, management circuit, magnet and Hall element. It exhibits a wide sensing range, great stability and excellent sensitivity for vehicle speed sensing and vehicle braking monitoring. The self‐powered Hall vehicle sensor proposes a promising solution for speed sensing and braking monitoring, and indicates the potential applications of power‐tribotronics for self‐powered electronic devices in the prospective automobile industry.
