Optical Fiber‐Based Versatile Wearable Force Myography System: Application to Human–Robot Interaction

Year: 2025

Type: article

Abstract: This article presents a novel, versatile wearable force myography (FMG) system based on optical fiber technology, designed for high sensitivity and mechanical robustness. Unlike conventional FMG systems, which are susceptible to environmental interference, the proposed system utilizes light loss through controlled fiber–polymer contact to achieve stable and noise‐free signal transmission. Its compact and flexible form factor allows seamless integration into wearable devices, facilitating muscle‐activity monitoring under diverse real‐world conditions, including biologically challenging scenarios such as sweating. Experimental evaluations highlight the system's ability to detect even micronewton‐scale forces and accurately recognize multiple gestures. Furthermore, the system can estimate joint angles, including those of individual fingers, which underscores its potential for precise motion capturing and continuous tracking. Overall, the proposed FMG system represents a promising solution for a wide range of practical human–robot interaction applications.
