Abstract

A novel protein-based polymer memristor is synthesized by a polymerization reaction using silk fibroin protein (SFP) and 2-isocyanatoethyl methacrylate. The analogue-type protein-based memristor demonstrates that more than 32 conductance levels are impressively obtained and outstandingly maintained for 4 months. This work provides a new horizon for high performance analogue computing systems.
