Plasma‐Induced Wrinkle‐Crack Dual Structure for Robust Directional Strain Sensing in Dynamic Motion Perception

Small, Journal Year: 2025, Volume and Issue: unknown

Published: April 14, 2025

Abstract Flexible multi‐directional sensors hold vast potential for complex application scenarios, yet creating sensitive, stable, and linear strain capable of flexibly detecting remains a significant challenge. Here, plasma‐induced wrinkle‐crack dual structure is introduced force detection high‐reliability flexible sensors. By combining pre‐stretching oxidative plasma bombardment, multi‐layer exhibits film stress engineering with varying elastic moduli established on the surface elastomer. The rigid silicon oxide hardened layer induces shear at pre‐stretched interface. Periodic wrinkles are generated upon release from pre‐stretching, which not only suppresses crack propagation but also significantly enhances linearity between signal applied force, thanks to conductive network's wrinkles. adjusting direction under treatment, morphology orientation sensitive can be effectively controlled. coexisting parallel wrinkle perpendicular structures impart anisotropic properties, improving sensor's directional capabilities. With high gauge factor (GF = 454), excellent cyclic durability (over 100 000 cycles), capability, this sensor demonstrates promising applications in wearable electronics robot motion detection, positioning it as next‐generation sensor.
