A research team from China and the U.K. has produced a memristor-like device made from egg proteins, magnesium, and tungsten.

Jikui Luo, Xiaozhi Wang, and colleagues spun diluted albumen, the clear liquid within an egg, to form it into an ultra-thin film for use as the dielectric in an integrated circuit. Magnesium and tungsten top and bottom electrodes are used to fabricate water-soluble memristors arranged in a 4-by-4 cross-bar configuration.

Testing demonstrated the device's performance matched that of non-degradable memristors. Under dry conditions in the lab, the components worked reliably for more than three months. In water, the electrodes and albumin dissolved in two to 10 hours in the lab. The rest of the chip took about three days to break down, leaving minimal residues behind.

The researchers say biocompatible and dissolvable electronic devices will be useful for bioelectronics and environment sensors used in the Internet of Things.
