Reconfigurable perovskite nickelate electronics for AI. Another twist for doing AI hardware. "The hardware is a small, rectangular device made of a material called perovskite nickelate, which is very sensitive to hydrogen. Applying electrical pulses at different voltages allows the device to shuffle a concentration of hydrogen ions in a matter of nanoseconds, creating states that the researchers found could be mapped out to corresponding functions in the brain."

"When the device has more hydrogen near its center, for example, it can act as a neuron, a single nerve cell. With less hydrogen at that location, the device serves as a synapse, a connection between neurons, which is what the brain uses to store memory in complex neural circuits."

"Through simulations of the experimental data, the team's collaborators showed that the internal physics of this device creates a dynamic structure for an artificial neural network that is able to more efficiently recognize electrocardiogram patterns and digits compared with static networks. This neural network uses 'reservoir computing,' which explains how different parts of a brain communicate and transfer information."

The brain's secret to lifelong learning can now come as hardware for artificial intelligence
