Synaptic transistor learns as it switches
Materials scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have created a transistor that behaves like a biological synapse by adapting physically to changing signals.
with speed comes the penalty of power dissipation. With electronics becoming more and more powerful and ubiquitous, you could have a huge impact by cutting down the amount of energy they consume."

The extreme sensitivity of electrical properties to defects in correlated oxides may make them a particularly suitable class of materials to realize artificial biological circuits that can be operated at and above room temperature and integrated into conventional electronic circuits.

"In this paper, we demonstrate high-temperature operation, but the beauty of this type of a device is that the learning behavior is more or less temperature insensitive, and that’s a big advantage," said Ramanathan. "We can operate this anywhere from about room temperature up to at least 160 degrees Celsius."

The synapse performance in this proof-of-concept device is partially dependent on physical scale. Ramanathan and his research team are planning, along with microfluidics experts at Harvard, to investigate limits of miniaturization and performance.
