Flexible pressure sensors have garnered significant attention due to their wide range of applications in human motion monitoring and smart wearable devices. However, the fabrication that offer both high sensitivity a detection remains challenging task. In this paper, we propose an AgNW-coated PDMS flexible piezoresistive sensor based on gradient-wrinkle structure. By modifying microstructure PDMS, demonstrates varying sensitivities responses across different ranges. The wrinkle contributes (0.947 kPa−1) at low pressures, while film with gradient contact height ensures continuous change area through gradual activation wrinkles, resulting (10–50 kPa). This paper also investigates state films under pressures further elaborate sensor’s sensing mechanism. excellent performance real-time response touch behavior, joint motion, swallowing behavior recognition, grasping highlights its broad application prospects human–computer interaction, monitoring, intelligent robotics.

Abstract Artificial ears with intelligence, which can sensitively detect sound—a variant of pressure—and generate consciousness and logical decision‐making abilities, hold great promise to transform life. However, despite the emerging flexible sensors for sound detection, most success is limited very simple phonemes, such as a couple letters or words, probably due lack device sensitivity capability. Herein, construction ultrasensitive artificial eardrums enabling intelligent song recognition reported. This strategy employs novel geometric engineering sensing units in soft microstructure array (to significantly reduce effective modulus) along complex exploration leveraging machine learning algorithms. Unprecedented pressure (6.9 × 10 3 kPa −1 ) demonstrated sensor hollow pyramid architecture porous slants. The integrated exhibits unparalleled (exceeding by 1–2 orders magnitude compared reported benchmark samples) detection sensitivity, accurately identify 100% (for training set) 97.7% test database segments from 77 songs varying language, style, singer. Overall, results highlight outstanding performance hollow‐microstructure‐based sensor, indicating its potential applications human–machine interaction wearable acoustical technologies.
