A network of four spintronic oscillators can successfully be trained to recognize different spoken vowels, says a team of researchers at C2N and CNRS/Thales in France and AIST in Japan. Each of the nanoscale devices in the network acts like a nano-neuron and behaves just like its biological counterpart in that it can fire rhythmically in a controlled way and even oscillate in unison with the other devices present. The new network is an important step forward for neuromorphic computing based on spintronics.
