Researchers develop perovskite-based memristors that are more powerful and easier to manufacture
The human brain can effortlessly process complex sensory information and learn from experiences, while a computer cannot. And, the brain does all this by consuming less than half as much energy as a laptop. One of the reasons for the brain's energy efficiency is its structure. The individual brain cells – the neurons and their connections, the synapses – can both store and process information. In computers, however, the memory is separate from the processor, and data must be transported back and forth between these two components. The speed of this transfer is limited, which can slow down the whole computer when working with large amounts of data.
One possible solution to this problem are novel computer architectures that are modeled after the human brain. To this end, scientists are developing 'memristors': components that, like brain cells, combine data storage and processing. A team of researchers from Empa, ETH Zurich and the Politecnico di Milano has developed a memristor based on perovskite materials that is more powerful and easier to manufacture than its predecessors.
