Memristor Breakthrough: First Single Device To Act Like a Neuron

spectrum.ieee.org
  • With DC voltage input, the first neuron-like device outputs not just simple spikes, but a whole array of neural activity, like bursts of spikes and self-sustained oscillations.
  • It took five years to develop this “little piece of nanoscale material structure”, and it combines resistance, capacitance, and Mott memristance.
  • Materials in Mott transition switch between insulating and conducting based on temperature, a property known since the 1960’s, only recently explored in devices.
  • The transition requires a nanoscale layer of a material - this one uses niobium oxide, but the creators want to try other materials that transition at different temperatures.
  • Finding the right material is just one of many challenges of making this device practical, but it could lead to machines that are as powerful as our brains.
