Abstract
Nowadays, the demand for smart wearable devices has been increasing significantly. Integrating multiple functions into a single sensor has become a continuous challenge for researchers. To address these issues, a novel two-dimensional material, MXene (Ti3C2Tx), is now being utilized to fabricate flexible multifunctional sensors. TPU (thermoplastic polyurethane) fiber mats are prepared through electrospinning. Using TPU fiber mats as the substrate, MXene/TiO2/Ru composites are synthesized through a simple and effective method and loaded onto the fiber mats. Experimental tests have revealed that the TPU/MXene/TiO2/Ru flexible sensor exhibits characteristics such as a large stretching range, good durability, high sensitivity, and excellent breathability. The response of the TPU/MXene/TiO2/Ru flexible sensor can reach up to 80.4 k when it is stretched to 120 % of its original length at a stretching speed of 0.5 mm/s. Moreover, this sensor can be used to detect movements in human wrists, arms, faces, legs, fingers, and even vocal cord vibrations, responding to voice recognition through specific word combinations. Furthermore, this sensor exhibits a maximum response of 15.06 % to 100 ppm NH3 at room temperature, accompanied by high selectivity and stability, indicating its excellent multifunctionality in the fields of human health and environmental protection.
