Their nanofluidics system is based on materials called “correlated electron oxides”, which can switch between being electrical conductors and insulators when a tiny charge is applied, and keep that state even when unpowered.
“We are using tiny currents of ions of atoms generated by these electrical signals to change the state of matter of this oxide material,” lead researcher Stuart Parkin told Venturebeat.
He added: “It is a means to build low-energy, highly efficient devices by turning on and off their conducting state. We turn this material into a metal and maintain it without any need to supply power.”
The system mimics how the brain operates, leading to hopes that the technology could be used to replicate the brain’s remarkable efficiency. As a side benefit, it could also dramatically reduce the power consumption of mobile devices.
The research was published in Science.
