Creating intelligent active deformation using soft actuators and structures for flexible electronics and soft robotics.
An electrically controlled self-bendable film that transforms into various 3D structures—triangles, helices, cubes, and pyramids—through precise design parameters. Successfully demonstrated in a flexible display that bends on command and a soft robotic hand with active grip control.
