In recent years, the automotive industry has made significant progress in integrating multifunctional sensors to improve vehicle performance, safety, and efficiency. As the number of integrated sensors keeps increasing, there is a growing interest in alternative energy sources. Specifically, self-powered sensor systems based on energy harvesting are drawing much attention, with a main focus on sustainability and reducing reliance on typical batteries. This paper demonstrates the use of triboelectric nanogenerators (TENGs) in a computer mouse for efficient energy harvesting and in automobile braking systems for safety applications using SrBiTaO (SBTO) perovskite, blended PDMS composite operating in free-standing mode with an interdigitated patterned aluminum electrode. This self-powered sensor is capable of distinguishing between normal and abnormal braking patterns using digital signal processing techniques. It is noteworthy that the addition of 15% wt. of the SBTO in PDMS composite-based TENG delivered 13.5 V, 45 nA, and an output power of 0.98 µW. This new combination of energy harvesting and safety applications enables real-time monitoring and predictive maintenance in the automotive industry.
近年来，汽车行业在集成多功能传感器方面取得了重大进展，以提高车辆的性能、安全性和效率。随着集成传感器数量的不断增加，人们对替代能源的兴趣日益浓厚。具体来说，基于能量收集的自供电传感器系统引起了广泛关注，主要关注可持续性和减少对典型电池的依赖。本文展示了在计算机鼠标中使用摩擦纳米发电机 (TENG) 进行高效能量收集，以及在汽车制动系统中使用 SrBiTaO (SBTO) 钙钛矿，混合 PDMS 复合材料在自由站立模式下运行，带有叉指式图案化铝电极，用于安全应用。这种自供电传感器能够使用数字信号处理技术区分正常和异常制动模式。值得注意的是，在 PDMS 复合材料基 TENG 中添加 15%wt 的 SBTO 可提供 13.5 V、45 nA 和 0.98 µW 的输出功率。这种能量收集和安全应用的新组合使汽车行业能够实现实时监测和预测性维护。
