柔性电子产品在可穿戴电子产品和人机接口方面引起了极大的兴趣。在这里，已经展示了没有顶部栅电极的柔性有机摩擦电子晶体管（FOTT）。FOTT是在柔性聚对苯二甲酸乙二醇酯薄膜上制作的，分别使用p型并五苯和聚（甲基丙烯酸甲酯）/Cytop复合材料作为导电通道和介电层。电介质层和移动的摩擦电层之间的接触起电可以调制电荷载流子。基于制作的FOTT，压力和磁传感器已分别开发，表现出高灵敏度，快速响应时间，和良好的稳定性。这种结构简单的FOTT显示了摩擦电子学在人机交互、电子皮肤、可穿戴电子、智能传感等方面的巨大潜力。
Flexible electronics has attracted enormous interest in wearable electronics and human–machine interfacing. Here, a flexible organic tribotronic transistor (FOTT) without a top gate electrode has been demonstrated. The FOTT is fabricated on a flexible polyethylene terephthalate film using the p-type pentacene and poly(methyl methacrylate)/Cytop composites as the conductive channel and dielectric layer, respectively. The charge carriers can be modulated by the contact electrification between the dielectric layer and a mobile triboelectric layer. Based on the fabricated FOTT, pressure and magnetic sensors have been developed, respectively, that exhibit great sensitivity, fast response time, and excellent stability. The FOTT in this simple structure shows bright potentials of tribotronics in human–machine interaction, electronic skins, wearable electronics, intelligent sensing, and so on.
