Organic memristive element with Chitosan as solid polyelectrolyte

The biomimetic devices such as the artificial synapses are of great significance because they can emulate the functions of biological systems. The development of memristive devices represents one of the most promising pathways towards adaptive and neuromorphic computing. This study reports the characterization of the first organic memristive element based on polyaniline-Chitosan (PANI–CS) junction. The Chitosan is used as solid polyelectrolyte in the active area of organic memristive element. Its working principle is based on the significant variation of the resistance of PANI in the oxidized and reduced states in junction area. The experimental parameters that influence the memristive behavior of Chitosan-based devices were studied by means of voltage-current measurements. The application of biocompatible material, the Chitosan, in organic memristive devices pave the way towards the application of organic memristor in bio-integrated systems.
