Hydrogels are water-based biomaterials developed specifically for human use, according to a Biomaterials journal article. They are a water-swollen polymeric material that doesn’t change its distinct 3D structure. They are formed from super-absorbent, chain-like polymers and are not soluble in water. However, their porous surface allows for nutrients and cell waste to pass through. They have shown the…
MIT creates gentle robot that works using water
Massachusetts Institute of Technology engineers have created a robot that is made of hydrogels and powered by water that has the potential to be used in surgical applications. Tough, rubbery and mostly water, these robots can perform an array of tasks including kicking a ball or grabbing and releasing live fish. The transparent robots move…
