However, existing clinical systems are constrained by motion limitations, complexity, and cost, hindering daily use. In this work, we present a bio-inspired, low-cost, flexible, and self-powered respiration sensor (BLFS-RS) inspired by the fish lateral line system, operating via contact electrification and electrostatic induction. It features a semicylindrical structure made of silicone rubber, incorporating bionic air channels and a porous-villus composite microstructure. It detects respiratory forces by deforming with abdominal cavity fluctuations, enabling respiration monitorResearch (Washington, D.C.)0905https://www.ebi.ac.uk/biostudies/studies/S-EPMC12457744biostudies-literatureFlexible Self-Powered Respiration Sensor Inspired by Fish Lateral Line Systems.PMC12457744Liu XGu CYu BRen LBa KZhang YWang DShi GZhang MHan ZShen HMa GfalseFlexible Self-Powered Respiration Sensor Inspired by Fish Lateral Line Systems.Respiration is a critical physiological signal, and abnormal respiratory patterns are widely recognized as key indicators of various cardiopulmonary and neurological disorders, making continuous monitoring crucial.
