外文摘要：In recent years, flexible capacitive sensors have been widely applied in fields such as health monitoring, electronic skin, and artificial intelligence. To address the issues of low sensitivity and narrow sensing range in flexible capacitive sensors, a dual-mode non-contact-pressure sensor with a core-shell structure based on ionic liquid/porous elastic rope was designed, and its surface morphology and performance were tested and analyzed. The results indicate that the sensor exhibits high sensitivity (0.0137 cm?1), a linearity of up to 0.9959, and a wide response range (0-14 cm) in non-contact sensing. For pressure sensing, the sensor demonstrates high sensitivity (0.0255 kPa?1), fast response time (70 ms), a wide response range (0-88.6 kPa), and good cycle stability. Owing to these excellent properties, the dual-mode sensor can achieve real-time monitoring of human movements (such as pressing, joint movements, swallowing, etc.), indicating its broad application prospects in the field of smart wearables. ? 2025 Beijing University of Aeronautics and Astronautics (BUAA).
