MXene/TMD Nanohybrid for the Development of Smart Electronic Textiles Based on Physical Electromechanical Sensors

Wearable technologies are becoming gradually prevalent as a personal health system, facilitating unceasing real-time monitoring of human health on a regular basis and outside the clinical environments. In this perspective, an urgent requirement for extensively sensitive and wearable sensors has increased to examine health during life activities. The fabrication of Ti3C2Tx/SnSe2 nanohybrid E-textile based multifunctional physical sensors (pressure, strain) on the cotton substrate to monitor an individual's health during daily activities is demonstrated here. The fabricated nanohybrid E-textile based physical sensors display an extraordinary sensitivity of 14.959 kPa(-1) in the applied pressure range of 1.477-3.456 kPa and a gauge factor of 14.108 for 5-25% of applied strain. In addition, these physical sensors show exceptional stability of approximate to 2500 cycles for a pressure sensor and approximate to 3000 cycles for a strain sensor which signifies the sturdiness of the sensor. Detailed underlying physics and transduction mechanism are explained by Schottky barrier and tunneling resistance mechanism. Further, an android/iOS/web-based app is developed to validate wireless integration of the fabricated multifunctional physical sensors for demonstration toward smart shoe and crepe bandage applications.
