Mechanoelectrical metamaterial-enabled ultrasensitive pressure sensing over a broad dynamic range

Abstract

Flexible pressure sensors face a trade-off between sensitivity and range. A dual-gradient mechanoelectrical metamaterial with molecular ferroelectrics achieves 320 mV/kPa sensitivity and 1.3 Pa–3.45 MPa range via adaptive lattice reconfiguration, enabling robotic tactile perception and food quality assessment while establishing a structure-centric design paradigm for next-generation high-performance sensors.
