Published: Jan. 30, 2025

Abstract Research on flexible strain sensors has grown rapidly and is widely applied in the fields of soft robotics, body motion detection, wearable sensors, health monitoring, sports. In this study, MXene was successfully synthesized powder form combined with multi-walled carbon nanotube (MWCNT) to develop MWCNT@MXene conductive network-based silicone rubber (SR) substrate. Combining MWCNTs as a material been shown significantly improve sensor performance, due MXene’s high conductivity properties that strengthen MWCNT pathway, increase sensitivity, stability. The fabricated by sandwich method consisting three layers, which enables more accurate reliable detection changes. main innovation research utilization optimizes performance overcomes limitations previous materials, makes it effective solution for long-term applications. Furthermore, evaluated test its through linearity, response time, durability tests. results showed exhibited excellent sensitivity 39.97 over range 0-100% linearity (0.99) 0–50%. also fast time about 70 ms, good stability during low (1–5%) (20–100%) cycle testing can withstand up 1200 loading unloading cycles. addition, effectively detects wide movements, including finger, wrist knee movements. These findings show electromechanical are improved use material, so these considered promising applications wearables monitoring.
