Wearable 3D Meshed Textile Pressure Sensor for Physiological Signal Monitoring

Wearable electrical textiles are of great value for future personalized healthcare applications. Herein, we report a 3D meshed textile pressure sensor, using facile dip coating strategy, that combing the sensitive two-dimensional Ti ₃ C ₂ T _x MXene nanolayer with woven textile fibers. Based on the sensitive 3D cross-connected conductive network, the textile sensor achieves simultaneously a high sensitivity of up to 81.9 kPa ^-1 and a fast response time of 30 ms in a wide pressure detection range (0-19 kPa) as well as prominent durability of more than 5000 cycles. Benefiting from superior performances, the textile sensor can be applied for real-time human physiological signals monitoring from pulse wave to human joint motion. This work represents a solid step toward personalized healthcare and clinical diagnosis.
