摘要

成功地设计、制造了一种新型的基于e-Gear选择器的单电极摩擦纳米发电机(TENG),并在柔性衬底上进行了测试。该装置由代表传统换挡选择器(P、R、N和D)的四个TENG传感器组成。分别选择皮革、棉花、纸张和热塑性聚氨酯(TPU)作为TENG 1-4的底层摩擦电层。银(Ag)油墨丝网印刷在每层代表单个电极的背面。选择人体皮肤作为最上面的摩擦电层。根据材料的选择,每个TENG设备产生不同的输出电压,从而可以选择预期的齿轮模式,而无需复杂的控制算法。用开路电压(${V} _{\text {oc}}$)和短路电流(${I} _{\text {sc}}$)表征TENG装置。通过制作每个TENG装置的三个样品并对每个TENG装置进行三次测试来评估TENG装置的重复性和再现性。平均${V} _{\text {oc}}$为$4.27~\pm ~0.36$、$7~\pm ~0.31$、$9.05~\pm ~0.21$和$12.38~\pm ~0.34$ Vpp,得到的功率密度分别为$0.37~\pm ~0.05$、$0.72~\pm ~0.09$、$0.95~\pm ~0.07$和$1.74~\pm ~0.10~\mu $ W/cm2。e-Gear选择器的性能展示了TENG能量收集方法整合到汽车行业的潜力,与电动汽车(EV)应用的快速发展保持一致。这项技术在未来的齿轮选择器设计中尤其有前景,因为它消除了对外部电源的需求,降低了成本,最大限度地减少了布线,并在车辆内提供了更大的灵活性。

Development of Self-Powered e-Gear Selector Based on Single-Electrode Triboelectric Nanogenerator (TENG) Technology
A novel e-Gear selector single-electrode-based triboelectric nanogenerator (TENG) was successfully designed, fabricated, and tested on flexible substrates. The proposed device consists of four TENG sensors representing the traditional gear shift selector (P, R, N, and D). Leather, cotton, paper, and thermoplastic polyurethane (TPU) were selected as bottom triboelectric layers for TENGs 1–4, respectively. Silver (Ag) ink was screen-printed on the backside of each layer representing the single electrode. Human skin was chosen as the top triboelectric layer. Based on the selection of the materials, each TENG device generates different output voltages, enabling the selection of the intended gear mode without the need for a complex control algorithm. The TENG device was characterized in terms of open-circuit voltage ( ${V} _{\text {oc}}$ ) and short-circuit current ( ${I} _{\text {sc}}$ ). The repeatability and reproducibility of the TENG device were evaluated by fabricating three samples of each TENG device and by testing each TENG device three times. An average ${V} _{\text {oc}}$ of $4.27~\pm ~0.36$ , $7~\pm ~0.31$ , $9.05~\pm ~0.21$ , and $12.38~\pm ~0.34$ Vpp, resulted in a power density of $0.37~\pm ~0.05$ , $0.72~\pm ~0.09$ , $0.95~\pm ~0.07$ , and $1.74~\pm ~0.10~\mu $ W/cm2, was measured for TENGs 1–4, respectively. The performance of the e-Gear selector showcased the potential of the TENG energy harvesting method for integration into the automotive industry, aligning with the rapid advancements in electric vehicle (EV) applications. This technology is particularly promising for future gear selector designs, as it eliminates the need for external power supplies, reduces cost, minimizes wiring, and offers greater flexibility in positioning within the vehicle.
