The wearable strain sensors with multifunctional applications can fuel the rapid development of human–machine intelligence for various sectors like healthcare, soft robotics, and Internet of Things applications. However, achieving the low‐cost and mass production of wearable sensors with ultra‐high performance remains challenging. Herein, a simple, cost‐effective, and scalable methodology to fabricate the flexible and highly sensitive strain sensors using carbon black and latex rubbers (LR) is presented. The LR‐based strain sensor demonstrates excellent flexibility, fast response (≈600 ms), ultra‐high sensitivity (maximum gauge factor of 1.2 × 104 at 250% strain), and long‐term stability over 1000 cycles. The LR‐based strain sensors are sensitive to monitor subtle human motions such as heart pulse rate and voice recognition along with high‐strain human joint operations. Additionally, the sensing mechanism of LR bands is investigated by surface topographies and electromechanical response under various strained/unstrained conditions. Further, a smart glove‐based sensor module made of LR strain bands with an Arduino reader for the human–machine intelligence device for non‐verbal communication in military applications is demonstrated.

超高灵敏度碳基导电橡胶，可实现柔性和可穿戴的人机智能感知
具有多功能应用程序的可穿戴应变传感器可以推动人机智能在医疗，软机器人和物联网应用等各个领域的快速发展。但是，要实现低成本和大量生产具有超高性能的可穿戴传感器仍然是一项挑战。本文介绍了一种简单，经济高效且可扩展的方法，以使用炭黑和乳胶橡胶（LR）来制造灵活且高度灵敏的应变传感器。基于LR的应变传感器具有出色的灵活性，快速响应（≈600ms），超高灵敏度（最大规格系数为1.2×10 4在250％的应变下）和1000周期内的长期稳定性。基于LR的应变传感器非常敏感，可以监测诸如心搏率和语音识别之类的细微人体运动，以及对人体的高应变操作。此外，通过在各种应变/非应变条件下的表面形貌和机电响应，研究了LR波段的感应机制。此外，还演示了一种基于智能手套的传感器模块，该传感器模块由LR应变带和Arduino读取器组成，用于人机智能设备，用于军事应用中的非语言通信。
