Wearable sensors directly incorporated into clothing or attached to the body have been widely studied in recent. However, the dilemma between sensitivity and sensing range of the sensors still hinders their broad applications in wearable electronics. Here, we present a sensor consisting of a stretchable fiber with braid-like structure and silver nanowires fabricated by a facile and cost-effective dip coating method. The fiber sensors could not only detect multiple deformations including tensile strain, torsion and bending, but also show high and steady sensitivity (Gauge factor ∼65) in a large sensing range (up to 100% strain). Additionally, the strain sensor also shows short creep recovery time (∼1 s) and good cycling stability. Finally, the fiber exhibits great ability of monitoring wrist pulse, recognizing pronunciation, sensing forearm muscle shrinkage and relaxation, and rectifying athlete’s sporting gestures.

直接结合到衣服上或附着在身体上的可穿戴式传感器近来已得到广泛研究。然而，传感器的灵敏度和感测范围之间的困境仍然阻碍了它们在可穿戴电子产品中的广泛应用。在这里，我们介绍了一种传感器，该传感器由具有辫状结构的可拉伸纤维和通过便捷且经济高效的浸涂法制造的银纳米线组成。光纤传感器不仅可以检测包括拉伸应变，扭转和弯曲在内的多种变形，而且还可以在较大的传感范围内（高达100％应变）显示出高而稳定的灵敏度（标尺系数〜65）。此外，应变传感器还显示出较短的蠕变恢复时间（约1 s）和良好的循环稳定性。最后，该纤维具有强大的监测腕部脉搏，识别语音，
