• • Sensitivity of 0.77 kPa−1 under 30 MPa hydrostatic pressure: This high sensitivity enables detection of small gripping forces (comparable to human touch) at depths up to 3000 m, directly addressing the bottleneck of manipulating delicate specimens in deep-sea environments.
• • Signal fluctuation below 1.48%: The sensor maintains stable performance under extreme pressure, ensuring reliable force feedback for precise manipulation tasks, which is critical for avoiding damage to collected samples and improving operational efficiency.
• • Tunable sensitivity and detection range via lattice parameters: Adjusting the lattice structure allows customization for specific depth and force requirements, providing a versatile platform for various underwater applications, from shallow to full-ocean-depth exploration.
• • Dual-curing DLP resin with micron-scale printing accuracy and seawater resistance: The material system enables rapid prototyping of complex geometries with mechanical properties comparable to thermoplastic resins, facilitating scalable manufacturing of durable deep-sea sensors.
