Origami Robots with Magnetic Muscles Revolutionize Medicine Delivery

Researchers at North Carolina State University have developed a new 3-D printing technique that can create paper-thin "magnetic muscles," which can be applied to origami structures to make them move. This innovation has the potential to transform medicine delivery, making it less invasive and more effective. The magnetic muscles can be used to create robots that can navigate through the human body, delivering medicine to ulcers without causing harm. The technology has also been used to create a crawling robot that can traverse obstacles up to 7 millimeters high and adapt to diverse terrains, including sand.
