Closed-loop control improved facial prosthesis actuation in reinforced DEAs
—
in EngineeringWhat the study found A model-based closed-loop controller for reinforced dielectric elastomer actuators was able to improve actuation performance for a facial prosthesis. The designed prosthesis showed a root mean square error of 2.06% in response to electromyography signals from the zygomaticus major muscle, which is responsible for smiling. Why the authors say this matters…
Soft actuators may benefit from human-like control mechanisms
—
in EngineeringWhat the study found Soft actuators have not yet been controlled in ways that fully use their viscoelastic properties, and the authors report that they share key mechanical characteristics with human muscles. The study links these similarities to computational mechanisms in the human nervous system that may support more effective control. What the authors say…
