An ICCSRR microwave sensor-electrothermal coupling flexible anti-/de-icing integrated array system

This paper presents an integrated flexible ice-sensing sensor array system based on microwave resonance. The system combines ice detection with electric heating de-icing, establishing a 3D electromagnetic model for the microwave resonator. A novel ICCSRR structure (evolved from CSRR) enables high-precision ice thickness detection (0-8 mm, ±0.1 mm resolution, <300 ms response). Innovatively, the resonant microstrip integrates with a flexible heating film to form a self-sensing-self-heating composite unit, using impedance phase characteristics for real-time de-icing feedback and dynamic power adjustment (6-10W). Its fully flexible design suits drone icing areas, while array-based detection provides multi-point ice shape data. Verified via an ice simulation-S21 testing platform, the system distinguishes 0.1 mm ice at -21°C, removes 4 mm ice within 10s at -20°C in high-power mode, and prevents icing via low-power pre-activation. Sensors offer synchronous de-icing progress feedback, demonstrating excellent ice-sensing and de-icing performance.
