Flexible pressure sensors are critical for advanced systems such as electronic skins and human-machine interaction. Among them, ionic capacitive have attracted widespread attention due to their exceptional flexibility sensitivity. However, variations in ambient temperature, humidity, operating circuit frequency significantly degrade the measurement accuracy of increase complexity subsequent signal processing. This paper proposes a capacitor structure based on Al-Al2O3-CB interface, which achieves temperature insensitivity (-5 °C-45 °C), humidity (20% RH-80% RH), (volatility <3% within range 100 kHz-1 MHz), while maintaining high sensitivity (24.62 kPa-1) fast response recovery time (33 ms/16 ms), this design can substantially reduce calibration sensor systems. The sensor's performance has been validated various application scenarios, including physiological monitoring, gesture recognition, robotic tactile sensing. By further integrating communication modules, system offers wheelchair control hand movement perception, providing enhanced accessibility convenience patients with muscular weakness other special needs.
