Squishy, Biodegradable Robots Pave the Way for Sustainable Electronics and 3d Printing

Takeaways:

• Researchers have developed a biodegradable ink (made out of gelatin, glucose, citric acid, and glycerol) that they use to 3D print soft robots.
• The gel can be re-used up to five times before it loses its mechanical properties after which it degrades without a trace.
• The researcher’s goal was to make a recyclable and biodegradable material which could be shaped into complex shaped and could be valuable for surgeries and interacting with humans and animals.
