Nowadays, with the rapid development of e-commerce, the transportation of products has become more and more frequent. However, how to monitor the situation of products effectively and conveniently during road transportation is a long-standing problem. In order to meet this problem in practical applications, we fabricated a triboelectric nanogenerator sensor with a "square box" structure (S-TENG) for detecting the vibration suffered by vehicles. Specifically, with the spring installed in the S-TENG as a trigger, the two friction layers can contact and then separate to generate the real-time electrical signals when the S-TENG receives external excitation. The output voltage signals of the S-TENG under different vibration states were tested and the results demonstrated that the peak and zero positions of the open-circuit voltage-output curve are related to amplitude and frequency, respectively. In addition, the subsequent simulation results, obtained by ANSYS and COMSOL software, were highly consistent with the experimental results. Furthermore, we built a platform to simulate the scene of the car passing through speed bumps, and the difference in height and the number of speed bumps were significantly distinguished according to the output voltage signals. Therefore, the S-TENG has broad application prospects in road transportation.
如今，随着电子商务的快速发展，产品运输越来越频繁。然而，如何在公路运输过程中有效且便捷地监测产品状况是一个长期存在的问题。为了在实际应用中解决这个问题，我们制备了一种具有“方盒”结构的摩擦纳米发电机传感器（S-TENG），用于检测车辆所受的振动。具体而言，S-TENG中安装的弹簧作为触发装置，当S-TENG受到外部激励时，两个摩擦层会接触然后分离，从而产生实时电信号。测试了S-TENG在不同振动状态下的输出电压信号，结果表明开路电压输出曲线的峰值和零点位置分别与振幅和频率有关。此外，通过ANSYS和COMSOL软件获得的后续模拟结果与实验结果高度一致。此外，我们搭建了一个模拟汽车通过减速带场景的平台，根据输出电压信号能够显著区分减速带的高度差异和数量。因此，S-TENG在公路运输中具有广阔的应用前景。
