Evaluating the Potential of Passive Exoskeletons in Modern Industries: A Comprehensive Analysis of the Impact on User Well-Being and Efficiency

This study investigates the application of passive exoskeletons in modern industries to enhance worker well-being and efficiency, especially in tasks prone to musculoskeletal issues. A specific protocol has been outlined to assess a passive exoskeleton (PAEXO back) through both objective and subjective analyses. The objective analyses focused on quantification on muscle activity, kinematic movements, and heart rate. Additionally, a preliminary study of skin conductance was carried out, since this parameter can directly disclose stress and exertion levels during task execution. On the other hand, the subjective analysis involved the use of questionnaires to quantify users’ impressions, aiming to understand the impact of using an exoskeleton on task performance. The results indicate that the PAEXO back exoskeleton demonstrates promise and could prove beneficial for workers engaged in strenuous tasks, reducing the risk of musculoskeletal injuries and enhancing ergonomics. Nonetheless, there is the necessity to refine the protocol and extend the familiarization period to facilitate the transition of the study into a real workplace scenario.
