Wearable strain sensors have attracted a lot of interests due to their unlimited prospects in applications such as human motion detections, electronic skin, and human–computer interactions. However, the complex manufacturing methods are generally used to fabricate the strain sensors with wide sensing ranges and high sensitivity. Herein, a high‐performance textile‐based strain sensor (TSS) is fabricated by one‐step screen‐printing method via transferring the silver nanowires ink onto a stretchable textile. Through designing the screen plate with various patterns, the optimized TSSs with different sensing ranges and sensitivity can be achieved simultaneously. Among them, a straight line‐structural TSS (with a width of 2 mm) exhibits a wide workable strain range of 120%, high gauge factor of 216, and superior durability (more than 2000 stretching/releasing cycles). As flexible wearable devices, these TSSs are used to monitor human joint motion, prefiguring the various applications in human health detection, soft robots, intelligent devices, etc.

单步打印，高灵敏度，基于纺织品的可调节性能应变传感器，用于人体运动检测

穿戴式应变传感器由于其在人体运动检测，电子皮肤和人机交互等应用中的无限前景而吸引了许多兴趣。然而，通常使用复杂的制造方法来制造具有宽感应范围和高灵敏度的应变传感器。在此，通过将银纳米线油墨转移到可拉伸的纺织品上，通过一步丝网印刷方法制造了一种高性能的纺织品基应变传感器（TSS）。通过设计具有各种图案的筛板，可以同时实现具有不同感应范围和灵敏度的优化TSS。其中，直线结构的TSS（宽度为2 mm）表现出120％的宽工作应变范围，216的高应变系数，和卓越的耐用性（超过2000次拉伸/释放循环）。这些TSS作为柔性可穿戴设备，用于监视人体关节运动，预示了人体健康检测，软机器人，智能设备等各种应用。
