Versatile Electronic Textile Enabled by a Mixed‐Dimensional Assembly Strategy

Abstract Electronic textiles (e‐textiles) hold great promise for serving as next‐generation wearable electronics owing to their inherent flexible, air‐permeable, and lightweight characteristics. However, these e‐textiles are of limited performance mainly because of lacking powerful materials combination. Herein, a versatile e‐textile through a simple, high‐efficiency mixed‐dimensional assembly of 2D MXene nanosheets and 1D silver nanowires (AgNWs) are presented. The effective complementary actions of MXene and AgNWs endow the e‐textiles with superior integrated performances including self‐powered pressure sensing, ultrafast joule heating, and highly efficient electromagnetic interference (EMI) shielding. The textile‐based self‐powered smart sensor systems obtained through the screen‐printed assembly of MXene‐based supercapacitor and pressure sensor are flexible and lightweight, showing ultrahigh specific capacitance (2390 mF cm −2 ), robust areal energy density (119.5 µWh cm −2 ), excellent sensitivity (474.8 kPa −1 ), and low detection limit (1 Pa). Furthermore, the interconnected conductive MXene/AgNWs network enables the e‐textile with ultrafast temperature response (10.4 °C s −1 ) and outstanding EMI shielding effectiveness of ≈66.4 dB. Therefore, the proposed mixed‐dimensional assembly design creates a multifunctional e‐textile that offers a practical paradigm for next‐generation smart flexible electronics.
