The stretchable, skin-mountable and wearable strain sensors are much desired for many applications, including human motion signals detection and physiological signals monitoring, and so forth. However, the fabrication of wearable strain sensors with high sensitivity, broad sensing range, and excellent comfort in a low-cost method remains a challenge. In this work, a high-performance strain sensor composed of a kind of nylon fabric and a two-dimensional layered nanomaterials-MXene (Ti₃C₂T_x) is reported. The thin nylon fabric has good stretchability and air permeability being available for wearable devices. The MXene as electrode material exhibits an excellent conductivity and hydrophilicity, which can be well adhered to the fabric. By integrating the advantages of MXene and fabric, the gauge factor of this as-prepared sensor can be up to 24.35 and 5.98 within the strain range of 20 % in the axial and radial of nylon fabric, respectively. Meanwhile, the sensor possesses high durability (>500) and good fastness to washing. Finally, a sleeve-shaped strain sensor that can well fit the human body is fabricated using a simple patterning impregnation method to detect subtle or large body movements.

对于许多应用，包括人体运动信号检测和生理信号监视等，非常需要可拉伸，可安装在皮肤上且可穿戴的应变传感器。然而，以低成本方法制造具有高灵敏度，宽感测范围和出色舒适度的可穿戴应变传感器仍然是一个挑战。在这项工作中，一种高性能的应变传感器由一种尼龙织物和二维分层纳米材料-MXene（Ti ₃ C ₂ T _x）被报告。尼龙薄织物具有良好的拉伸性和透气性，可用于可穿戴设备。作为电极材料的MXene具有出色的导电性和亲水性，可以很好地粘附到织物上。通过结合MXene和织物的优点，在尼龙织物的轴向和径向应变范围为20％时，这种传感器的规格系数分别可以达到24.35和5.98。同时，该传感器具有很高的耐久性（> 500）和良好的耐洗牢度。最后，使用简单的图案浸渍方法制造出可以很好地适合人体的袖子形应变传感器，以检测微小或较大的身体运动。
