Soft, submersible memory device created...

A new soft and squishy digital memory device prototype can be bent, dropped, or even placed underwater without suffering any damage.

Developed by researchers at North Carolina State University, the device consists of four crossed metal strips made of a liquid alloy of gallium and indium and set on the sides of slabs of a water based gel. The alloy strips act as the electrodes, creating a oxidized, non-conductive skin when exposed to a positive charge and losing that skin when when exposed to a negative charge. The gel is biocompatible, and could be implanted to allow electronics to interface with biological systems.
