Russian scientists from the National Research Center "Kurchatov Institute" and the Ivanovo State University of Chemistry and Technology conducted experiments with organic memristors — a new generation of microelectronic elements that can mimic the operation of synapses in the human brain. These devices, thanks to their ability to simultaneously store and process information, promise significant breakthroughs in the field of neuromorphic computing and "computing-in-sensor".
To modify the parameters of memristors, the researchers used a non-nucleotide analog of vitamin B12 — aquacyanocobinamide. It was added to the electrolyte solution, which made it possible to change the voltage at which the memristor switches. As a result of the experiments, it was found that increasing the concentration of this substance reduces the voltage required to switch the device, which brings its operation closer to biocompatible levels. This discovery could be an important step in the development of new devices that will be used in bioengineering, medicine, and intelligent computing.
The discovery makes it possible to significantly improve the characteristics of organic memristors and reveals their potential for creating technologies close to the functioning of the human brain.
