Perovskites, compounds with unique electronic properties previously confined to specialist applications, could enable neuromorphic computers that process and store data simultaneously, as human brains do. Halide perovskites can form memristors, circuit components whose electrical resistance switches between high and low states, allowing them to function as both artificial neurons and synapses in brain-like computing systems. Researchers expect to assemble prototype neuromorphic networks using perovskite-based memristors and capacitors within the next year, though commercial success remains uncertain
