4D-Printed Sulfur Waste Soft Robots Move Autonomously
Key Takeaways
- World's first 4D printing tech using industrial sulfur waste produces soft robots that autonomously move in response to heat, light, and magnetic fields
- New poly(phenylene polysulfide) polymer networks feature dynamic sulfur-sulfur bonds that enable full recyclability
- Platform turns a petroleum refining waste stream into compliant robots with potential medical and search-and-rescue applications
