In the field of biomimetic electronics, flexible sensors with both high resolution and large size are attracting a lot of attention. However, attempts to increase the number of sensor pixels have been thwarted by the need for complex inner circuits and the resulting interferences with the output. Technological challenges, such as real-time spatiotemporal mapping and long-time reliability, must be resolved for large-scale sensor matrices. This paper reports a simple and robust sensor with an arch-bridge architecture (ABA) to address these challenges. The device, which consists of an anti-icing all-transparent material system, is fabricated by immobilizing ABA ionic arrays on predefined grooves on the substrate. It systematically integrates ABA structure-designing, resistance-position-sensing, and parallel-addressing logic, allowing for an improvement of three orders of magnitude in the scanning speed (million-scale pixels) without logical “diagnose confusion.” In addition, it can withstand 100 000 stretching cycles without functional failure. It is also resistant to interferences from stretching. humidity, wet surfaces, and power lines. The proposed strategy is envisaged to serve as a general solution for high-density, large-area tactile sensors in various applications.

基于拱桥架构的无串扰、拉伸不敏感传感器，用于触觉映射，采用并行寻址策略实现百万级像素处理

在仿生电子领域，兼具高分辨率和大尺寸的柔性传感器引起了广泛关注。然而，由于需要复杂的内部电路以及由此产生的对输出的干扰，增加传感器像素数量的尝试受到阻碍。大规模传感器矩阵必须解决实时时空映射和长期可靠性等技术挑战。本文报道了一种简单而强大的具有拱桥架构（ABA）的传感器来应对这些挑战。该装置由防冰全透明材料系统组成，通过将 ABA 离子阵列固定在基板上的预定凹槽上而制成。它系统地集成了ABA结构设计、电阻位置传感和并行寻址逻辑，使扫描速度（百万级像素）提高了三个数量级，而没有逻辑“诊断混乱”。此外，它可以承受 100 000 次拉伸循环而不会出现功能故障。它还可以抵抗拉伸的干扰。湿度、潮湿的表面和电源线。所提出的策略预计将作为各种应用中高密度、大面积触觉传感器的通用解决方案。
