Programmable matter refers to materials that can change their physical properties or shape in response to external stimuli, such as light, heat, or electrical signals. This technology allows for the creation of objects that can adapt to different functions or environments, making them highly versatile. One of the key concepts in programmable matter is the use of tiny, interconnected units called smart particles or voxels. These units can communicate and work together to form complex structures, enabling applications in fields like robotics, medicine, and construction. The potential of programmable matter could revolutionize how we design and interact with physical objects.
