These soft actuators have several uses outside of virtual reality. They are a possible substitute for conventional actuators in automobiles, industrial machinery, and robots since they are small, quiet, and incredibly flexible in shape. According to the team, their adaptability and customization create opportunities for medical applications like prosthetics or assistive technology.
The recently created method increases the possibility of soft, responsive materials by printing long, elastic threads in addition to intricate structures. These developments may eventually result in actuators that closely resemble the way muscles work naturally, which would advance wearable technologies, robotics, and medical treatments.
“If we manage to make them just a little thinner, we can get pretty close to how real muscle fibers work,” said Dorina Opris, who leads the research group Functional Polymeric Materials at Empa, in a statement.
