Researchers Make Chip That Can Be Rewired Like the Human Brain

The chip is made from perovskite nickelate, which is very sensitive to hydrogen.

The chip can be reprogrammed on demand, which could help create artificial intelligence that learns continuously like the human brain.

A multi-institutional research effort created a reprogrammable-on-demand electronic chip, which could eventually lead to the creation a computer that learns continuously, like the human brain.

The chip is made from hydrogen-sensitive perovskite nickelate in order to adapt and learn in a way similar to the brain.

The researchers applied electrical impulses at different voltages to refine the concentration of hydrogen ions on the chip, generating states that could be mapped out to corresponding brain functions.

"Using our reconfigurable artificial neurons and synapses, simulated dynamic networks outperformed static networks for incremental learning scenarios," the researchers explained. "The ability to fashion the building blocks of brain-inspired computers on demand opens up new directions in adaptive networks."
