电子皮肤(e-Skin)提供了一个机械灵活的传感器网络，可以共形包裹不规则表面，并在空间上映射和量化各种刺激(1-12)。之前关于电子皮肤的工作主要集中在压力传感器与电子读数接口的优化上，而基于人类可读输出的用户界面却没有被探索过。在这里，我们报告了第一个用户交互的电子皮肤，它不仅在空间上映射施加的压力，而且通过内置的具有红色、绿色和蓝色像素的有源矩阵有机发光二极管显示器提供即时的视觉响应。在这个系统中，有机发光二极管(OLED)在接触表面的地方局部开启，发射的光的强度量化所施加的压力的大小。这项工作代表了塑料上的系统(4，13-17)演示，其中三个不同的电子组件-薄膜晶体管、压力传感器和OLED阵列-在单个塑料基板上大面积集成。报道的电子皮肤可能会在交互式输入/控制设备、智能墙纸、机器人和医疗/健康监测设备中找到广泛的应用。
Electronic skin (e-skin) presents a network of mechanically flexible sensors that can conformally wrap irregular surfaces and spatially map and quantify various stimuli(1-12). Previous works on e-skin have focused on the optimization of pressure sensors interfaced with an electronic readout, whereas user interfaces based on a human-readable output were not explored. Here, we report the first user-interactive e-skin that not only spatially maps the applied pressure but also provides an instantaneous visual response through a built-in active-matrix organic light-emitting diode display with red, green and blue pixels. In this system, organic light-emitting diodes (OLEDs) are turned on locally where the surface is touched, and the intensity of the emitted light quantifies the magnitude of the applied pressure. This work represents a system-on-plastic(4,13-17) demonstration where three distinct electronic components-thin-film transistor, pressure sensor and OLED arrays-are monolithically integrated over large areas on a single plastic substrate. The reported e-skin may find a wide range of applications in interactive input/control devices, smart wallpapers, robotics and medical/health monitoring devices.
