Large-area flexible pressure sensors are of paramount importance for various future applications, such as electronic skin, human-machine interfacing, and health-monitoring devices. Here, a self-powered and large-area integrated triboelectric sensor array (ITSA) based on coupling a triboelectric sensor array and an array chip of CD4066 through a traditional connection is reported. Enabled by a simple and cost-effective fabrication process, the size of the ITSA can be scaled up to 38 × 38 cm2 . In addition, unlike previously proposed triboelectric sensors arrays, which can only react to the dynamic interaction, this ITSA is able to detect static and dynamic pressure. Moreover, through integrating the ITSA with a signal processing circuit, a complete wireless sensing system is present. Diverse applications of the system are demonstrated in detail, including detecting pressure, identifying position, tracking trajectory, and recognizing the profile of external contact objects. Thus, the ITSA in this work opens a new route in the direction of large-area, self-powered, and wireless triboelectric sensing systems.

用于无线静态和动态压力检测和映射的大面积集成摩擦电传感器阵列。

大面积的柔性压力传感器对于各种未来应用至关重要，例如电子皮肤，人机界面和健康监测设备。在此，报告了基于通过传统连接将摩擦电传感器阵列和CD4066的阵列芯片耦合的自供电大面积集成摩擦电传感器阵列（ITSA）。通过简单且经济高效的制造工艺，ITSA的尺寸可扩展至38×38 cm2。此外，与先前提出的只能对动态相互作用做出反应的摩擦电传感器阵列不同，该ITSA能够检测静态和动态压力。此外，通过将ITSA与信号处理电路集成在一起，可以构成一个完整的无线传感系统。详细说明了该系统的各种应用，包括检测压力，识别位置，跟踪轨迹以及识别外部接触物体的轮廓。因此，ITSA在这项工作中开辟了一条向大面积，自供电和无线摩擦电传感系统方向发展的新途径。
