Hydrogel Hydrogels that can carry a charge could be used for future medical implants, soft batteries or other conductive materials. Wikimedia Commons
Future electronic skin and bio-batteries could be etched onto surfaces with inkjet printers, conducting electricity while looking for all the world like spongy biological tissue. A new electrically conductive hydrogel, developed at Stanford University, can be printed or sprayed as a liquid and turned into a gel once it’s in place.
