基于摩擦电纳米发电机的传感器已被广泛用于能量收集和传感应用，然而，多维信息感知和交互控制的应用是不够的。本文提出了一种利用摩擦电机制控制三维空间物体的超可拉伸摩擦电传感器（TSS）。这种结构简单、成本低廉的TSS主要由三个对称的传感器条和一个与之相连的移动的工作台组成。基于摩擦起电和静电感应的耦合效应，同一手指接触点的每一条长度变化，在两个端电极上产生不同的信号输出比，作为多维传感和控制的交互界面。因此，平行传感器条结构可以实现三个线性运动自由度和两个旋转运动自由度的感测和控制，并且所得到的感测范围为X、Y、Z、α和β（20 mm、20 mm、30 mm、36度和36度）。在操纵方面，这比具有刚性结构的常规控制器更简单，并且包括额外的空间维度。此外，演示的TSS作为人类纳米机器终端控制的纳米操纵器在扫描电子显微镜（SEM）成功地实现了10 nm的精度。所提出的TSS在自动化控制、机器人控制和物联网（IoT）中显示出巨大的应用潜力。
Sensors based on triboelectric nanogenerators have been widely used for energy harvesting and sensing applications, however, the applications of multidimensional information perception and interactive control are insufficient. In this paper, we present an ultra-stretchable triboelectric strip sensor (TSS) using triboelectric mechanism for controlling the objects in three-dimensional space. This facile and low-cost TSS is mainly composed of a parallel structure including three symmetric sensor strips fixed on the base and a mobile stage connected with them. Based on the coupling effect of triboelectrification and electrostatic induction, the length changes of each strip with the same finger contacting point generate different signal output ratios from two terminal electrodes, functioning as the interactive interface for multi-dimensional sensing and controlling. Hence, the parallel sensor strips structure can realize the sensing and controlling in three degrees of freedom of linear motion and two degrees of freedom of rotational motion, and resultant sensing ranges are X, Y, Z, alpha and beta (20 mm, 20 mm, 30 mm, 36 degrees, and 36 degrees). In terms of manipulation, this is simpler than the conventional controller with rigid structure and includes additional space dimensions. Furthermore, demonstration of the TSS as human-nanomachine terminal to control the nanomanipulator in scanning electron microscope (SEM) is successfully realized with the accuracy of 10 nm. The proposed TSS shows great potential for the applications in automated control, robotics control, and Internet of Things (IoT).
