Hydrogels are doing a brand-new dance now

Researchers 3-D printed tiny soft robots using a hydrogel that scientists can steer with an electric field. ↓↓More info and references below↓↓ Electroactive hydrogels—networks of water-loving polymers—swell and contract when electric fields alter the ion concentration in the solution surrounding them. By precisely controlling the dimensions of hydrogel structures, researchers could control how the hydrogels […]
