👉 Self-fluid, also known as self-folding or origami-inspired materials, is a class of smart materials that can change shape in response to external stimuli such as heat, light, or electricity without the need for mechanical actuators. These materials typically consist of thin, flexible layers that can be designed to fold or expand when triggered, mimicking the natural folding processes seen in biological systems like origami. This unique property allows self-fluid materials to transform from a compact, often flat state into complex, three-dimensional structures autonomously, opening up applications in fields ranging from biomedical devices and soft robotics to adaptive architecture and deployable structures.
