Triboelectric nanogenerator as a highly sensitive self-powered sensor for driver behavior monitoring

A pressure-sensitive, flexible and robust triboelectric nanogenerator (TENG) was used as a cost-effective sensing device for self-powered driver behavior monitoring. The sensitivity of TENG was evaluated preliminarily by detecting its open-circuit voltage signal in responding to externally enforced perturbation. A real-time monitoring system is demonstrated with TENGs, data-collecting unit and a driving simulator. A preliminary assessment of the real-time collected data demonstrates that the self-powered sensor is feasible for monitoring a driver's behavior.162
