Bio-inspired integrated pressure-sensing memory system using crack-based sensors and electro-mechanical metamaterials

, enabling reliable non-volatile information storage through mechanical state transitions. When applied pressure exceeds a predetermined threshold (approximately 2.6 mN), the memory component undergoes snap-through buckling, transitioning from a high-resistance "off state" to a low-resistance "on state" (≈110 Ω). Environmental durability tests demonstrate stable operation in various liquid media and temperatures up to 130 °C. A 4 × 4 integrated array successfully demonstrates spatial pressure mapping with selective memory writing above threshold pressures. This bio-inspired approach offers a promising pathway for developing intelligent tactile sensing systems for soft robotics, prosthetics, and human-machine interfaces.
