Pumping Iron: A Hydrogel Actuator with Mussel Tone

Protein from a small, tasty mollusk inspired Michigan Technological University’s Bruce P. Lee to invent a new type of hydrogel actuator.
Hydrogels are soft networks of polymers with high water content, like jello. Because of their soft, gentle texture, they have the potential to interact safely with living tissues and have applications in a number of medical areas, including tissue engineering. Lee, an assistant professor of biomedical engineering, wanted to make a hydrogel that wouldn’t just sit there.
