Development of an optical fiber force myography sensor for applications in human-robot interfaces

Abstract

The force myography (FMG) is the mechanical counterpart of the surface electromyography, in which the hand movements and forces are estimated from the radial pressure exerted by the forearm muscles, providing a robust and straightforward method for applications in teleoperation, prosthesis control, and human-robot interaction. In this sense, the project proposes the development of an optical fiber sensor system for postures identification by FMG. The wearable optomechanical transducers will be designed based on techniques such as light intensity modulation and specklegram analyses, with further characterization and refinements in order to achieve 10 N sensitivity and 100 ms dynamic response. Next, waveform features extraction procedures and artificial neural networks classifiers will be implemented for correlating the acquired FMG signals to the performed postures, with 90% target accuracy. Finally, the measurement system will be integrated with a virtual anthropomorphic manipulator for real-time control, so the robot behavior will be described by an event-driven finite state machine switched by the classifier output. The successful accomplishment of this project will provide a novel, robust, and low-cost technology for human-robot interaction, with further applications in bionic prostheses control and virtual reality systems, thus generating technical contributions to the fields of photonics, robotics, and automation, as well as multidisciplinary scientific results.
