The Innovation: 3D-Printed Magnetic Muscles
A new 3D printing technique allows the creation of paper-thin “magnetic muscles,” wich can be applied to origami structures to make them move. this innovation opens up possibilities for creating soft robots with precise control for a variety of applications.
Researchers at North Carolina State University 3D printed a thin magnetic film by infusing rubber-like elastomers with ferromagnetic particles. When exposed to a magnetic field, these films act as actuators, causing the origami structure to move without considerably interfering with its inherent motion.
Key advantages of the Technique
This approach offers a significant advantage over conventional magnetic actuators. Xiaomeng Fang, assistant professor in the Wilson College of Textiles and lead author of the research, explains:
“Traditionally, magnetic actuators use the kinds of small rigid magnets you might put on your refrigerator. You place those magnets on the surface of the soft robot, and they would make it move,” she says.
“With this technique, we can print a thin film which we can place directly onto the significant parts of the origami robot without reducing its surface area much.”
Targeted Drug Delivery: A Primary Request
The researchers designed a primary robot prototype to deliver medicine to ulcers inside the human body, leveraging the Miura-Ori origami pattern. This pattern allows a large flat surface to fold into a much smaller area, ideal for ingestion and subsequent deployment.
the magnetic “muscles” are strategically attached to facets of the origami structure. When exposed to a magnetic field, they facilitate the origami’s unfolding and navigation to the ulcer location. The Miura-Ori design is particularly well-suited for drug management as it can be ingested as a compact object and then expand to deliver medicine across its entire surface area.
