Development of low-cost, efficient, flexible and highly sensitive pressure sensors that can perceive and respond to environmental stimuli have become indispensable for wearable electronics. Herein, the Ti3C2Tx-textile based pressure sensor was successfully fabricated with the help of common fabric substrates by using simple and effective dipping-drying method. The Ti3C2Tx Nanosheets prepared by wet-chemical solution display excellent hydrophilicity, high specific surface area, metallic conductivity and controllable surface groups properties, which are extremely suitable in construction of low-cost and high-performance textile-based pressure sensors. And the Ti3C2Tx-textile based pressure sensor achieves high sensitivity (19.78 kPa(-1)), low detection limit (219 mN), fast response (similar to 149 ms) and well stability (more than 7000). With these merits, the Ti3C2Tx-textile based sensor is demonstrated to be able to recognize the human physiological signals, such as finger bending, tapping, hand movements and so on. Furthermore, the textile sensor also can be capable to measure pressure distribution and distinguish the subtle strain, which demonstrates great potential in both industrial and biomedical applications.
