MXene-enhanced non-wovenfabric medical flexible pressure sensor
Development of wearable flexible sensors for non-invasive and real-time physiological monitoring has become a research focus due to the increasing demand for health monitoring.An innovative approach for developing wearable and flexible sensors is proposed.The method employs environmentally friendly and cost-effective non-woven fabric as the matial of substrate.Through a simple dip-coating process,the natural microstructure of the non-woven fabric is combined with the excellent physicochemical properties of MXene,resulting in the successful fabrication of a MXene-modified non-woven fabric as the pressure-sensitive layer of pressure sensors.This flexible pressure sensor operate stably and has a wide sensing range,exhibiting ultra-high sensitivity(S1=0.5kPa-1 and S2=1.12kPa-1)within a pressure range of 0～150kPa,along with fast response and recovery times of 25ms and 50 msrily.The sensor can accurately capture radial artery pulse signals at the wrist,showing significant application potential in fields such as healthcare,sports training,and robotics.Additionally,it provides new insights for the development of low-cost and environmentally friendly sensors.
