New Jelly-Like Memory Device Works Well In Wet Conditions

Researchers over at the North Carolina State University have developed a soft memory device that works well even in wet environments.

According to the researchers, the development could open the door for bio-compatible electronic devices that can interact with cells and enzymes.

Dr. Michael Dickey, an assistant professor of chemical and biomolecular engineering at NC State, claims that a newly developed memory device has the properties of a Jell-O (that's jelly to those of us over the pond).

“We’ve created a memory device with the physical properties of Jell-O,” Dr. Dickey revealed.

Traditional electronic devices are rigid and don’t function in a wet environment. However, the Jell-O like memory device is extremely soft and is capable of working in extremely wet conditions.

The device, which is made from liquid alloy of gallium and indium metals set into water-based gels, can not hold huge amounts of memory at present, but is capable of working in environments that would be hostile for traditional devices.

“These properties may be used for biological sensors or for medical monitoring,” Dickey says. The applications of the technology could be huge and be used to create bio-compatible devices which interact with cells and tissues.
