Abstract
- Abstract Textile‐based wearable electronics combined with nanomaterials are ideal devices that have good electrical and thermal conductivity, and flexibility. With a metal conductivity and metalloid flexibility, 2D titanium carbide MXene is excellent enough for producing intelligent textiles. Here, a wrapping forming method is provided to fabricate MXene textile strain (MTS) sensors with high gauge factor (GF) of 715.94 as high as strain of 200%. Periodic cycling indicated that the MTS wrapped yarn is stable, which can track changes of facial expressions precisely as the small deformation. Weaving MTS yarns into fabric as glove and sensing belt can recognize sign language and record middle and large motions of human body, respectively. On the other hand, walking postures and electric heating are accurately detected by coating MXene dispersions on elastic and breathable spacer fabric as piezoresistive insoles, which is especially beneficial to the elderly and patients with foot diseases. Therefore, a unique strategy is proposed for full scale human motions monitoring by fabricating MXene helical yarns served as sensitive strain sensors, weft rib fabric that detected the in‐plane deformations and spacer fabric piezoresistive insole behaved as pressure sensors to monitor the step patterns so that suiting for wearable versatile sensing system.
