Wearable 3-D Meshed Textile Pressure Sensor for Physiological Signal Monitoring

Abstract

Wearable electrical textiles are of great value for future personalized healthcare applications. Herein, we report a 3-D meshed textile pressure sensor, using a facile dip coating strategy, that combing the sensitive 2-D Ti3C2Tx MXene nanolayer with woven textile fibers. Based on the sensitive 3-D 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 waves to human joint motion. This work represents a solid step toward personalized healthcare and clinical diagnosis.
