High-performance triboelectric nanogenerators (TENG), generally comprised of either a pair of surface-functionalized or dielectric modulated composite frictional layers, are technically unreliable from a commercial perspective, because of the complex fabrication procedures and configurations. This work projects a surface area enforced electrospun Nylon-6,6-based TENG as the vibrational energy scavenging and seat occupation detection system. The devised TENG can derive an output response of more than 300 μA of short circuit current, 350 V of open circuit voltage, and a power density of 550 mW m–2, which is the highest compared to previously reported Nylon-based dielectric-metal contact separation-based TENGs. The seat occupation sensing was successfully evaluated during a test drive on the TENG fitted vehicle. The charging up of a 1 μF capacitor to ∼30 V in 30 s marks the potential of Nylon-6,6 as a promising material for many applications, including smart transit.

用于自供电座椅监控应用的表面积增强型尼龙 6,6 纳米纤维工程摩擦纳米发电机

高性能摩擦纳米发电机(TENG)通常由一对表面功能化或介电调制的复合摩擦层组成,由于复杂的制造程序和配置,从商业角度来看,在技术上是不可靠的。这项工作将表面区域强制静电纺丝尼龙 6,6 基 TENG 作为振动能量清除和座椅占用检测系统。所设计的 TENG 可以得到超过 300 μA 的短路电流、350 V 的开路电压和 550 mW m –2的功率密度的输出响应,与先前报道的基于尼龙的介电金属接触分离的 TENG 相比,这是最高的。在安装 TENG 的车辆试驾期间,成功评估了座椅占用感应。1 μF 电容器在 30 秒内充电至 ∼30 V 标志着尼龙 6,6 作为许多应用(包括智能交通)的有前途的材料的潜力。
