Abstract
- Abstract: Growing demand in automobile safety system raises a requirement to electronic devices being self‐powered, stable, and durable. Herein, a self‐powered Hall vehicle sensor (SPHVS) is demonstrated for automobile safety system, which integrates the triboelectric nanogenerator, the management circuit, the magnet, and the Hall element. The tribotronic constant current source is proposed to steadily power the Hall element in rotational motion at any different speeds. Furthermore, the performances of the SPHVS for vehicle speed sensing and vehicle braking monitoring are systematically investigated, which exhibits wide sensing range, great stability, and excellent sensitivity. This work clearly proposes a promising solution for speed sensing and braking monitoring, and indicates the potential applications of power tribotronics for the self‐powered electronic devices in prospective automobile industry.
