A spintronic device measuring just 375 nm across has been used to recognize human speech. The device is a spintronic oscillator, which behaves much like a neuron in the brain. Created by physicists in France, Japan and the US, the system is described as the first neuromorphic computer that is based on a nanoscale device.
Neuromorphic computers try to emulate the human brain. As well as having the potential to be faster and more energy efficient than conventional computers, they could also excel at learning how to perform certain tasks – rather than being pre-programmed to do so.
