North Carolina State University researchers have developed a memory device that is soft, functions well in wet environments, and features “the physical properties of Jell-O,” according to Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State and co-author of a paper describing the research. The device’s pliable nature and biocompatibility could open up new possibilities for biocompatible electronic devices.

Prototypes have not yet been optimized to hold significant amounts of memory, but the technology holds promise for interfacing electronics with biological systems, such as cells, enzymes, or tissue. The devices are made using a liquid alloy of gallium and indium metals set in water-based gels, similar to gels used in biological research.
