Influence of the Physical Interface on the Quality of Human–Exoskeleton Interaction

Despite exoskeletons becoming widespread tools in industrial applications, the impact of the design of humanexoskeleton physical interfaces has received little attention. The present study aims at thoroughly quantifying the influence of different…
