Motor-free smart actuator achieves sub-second speed with near-perfect shape recovery

Summary

Korean researchers have developed a novel actuator combining shape memory alloys and polymers that bends when heated, achieving sub-second response times and nearly 100% shape recovery without complex motors. This represents a first-of-its-kind capability in smart actuator technology, with potential to simplify robotic designs and enable faster, more efficient motion in soft robotics and automation.
