可伸缩电子产品对下一代智能交互系统的发展具有重要意义。在这里，我们提出了一种没有顶栅电极的本征可伸缩有机摩擦电子晶体管(SOTT)，它由可伸展衬底、银纳米线电极、半导体混合物和非极性弹性体介质组成。SOTT的漏源电流可以通过与介质层的外部接触带电来调制。在平行和垂直于通道方向拉伸0-50%的情况下，SOTT保持了良好的输出性能。在拉伸到50%的数千次循环后，SOTT可以以极好的稳定性存活下来。此外，SOTT可以整合地附着在人类的手上，可以用于人机交互中的触觉信号感知，以及用于控制智能家居设备和机器人。这项工作实现了可伸缩的摩擦电子晶体管作为智能交互的触觉传感器，扩展了摩擦电子在人机界面、可穿戴电子和机器人方面的应用。
Stretchable electronics are of great significance for the development of the next-generation smart interactive systems. Here, we propose an intrinsically stretchable organic tribotronic transistor (SOTT) without a top gate electrode, which is composed of a stretchable substrate, silver nanowire electrodes, semiconductor blends, and a nonpolar elastomer dielectric. The drain-source current of the SOTT can be modulated by external contact electrification with the dielectric layer. Under 0-50% stretching both parallel and perpendicular to the channel directions, the SOTT retains great output performance. After being stretched to 50% for thousands of cycles, the SOTT can survive with excellent stability. Moreover, the SOTT can be conformably attached to the human hand, which can be used for tactile signal perception in human-machine interaction and for controlling smart home devices and robots. This work has realized a stretchable tribotronic transistor as the tactile sensor for smart interaction, which has extended the application of tribotronics in the human-machine interface, wearable electronics, and robotics.
