• • The one-layer nanofilm HI-CPS achieves an ultrahigh sensitivity of 9.40 kPa−1 and an ultralow detection limit of 0.1 Pa, enabling detection of subtle pressure changes critical for medical diagnostics and precision robotics.
• • The two-layer stacked nanofilm configuration maintains high sensitivity (3.17 kPa−1) while achieving excellent linearity (R2 = 0.999) over a broad working range (<5 kPa), ensuring accurate and reliable pressure mapping across a wide operational envelope.
• • The sensor demonstrates remarkable stability over 10,000 cycles, indicating robust mechanical durability essential for long-term wearable health monitoring and human-machine interfaces.
• • The successful implementation in monitoring human biological signals, sign language recognition, and basketball shooting gesture correction validates its practical utility in real-world applications, bridging the gap between laboratory performance and commercial viability.
