A Single Volatile VO2 Memristor Enabling Neuromorphic Perception, Learning, and Computing

Advanced Electronic Materials, EarlyView.
A single volatile VO2 memristor fabricated via atomic layer deposition is demonstrated as a multifunctional neuromorphic device enabled by intrinsic threshold‐switching dynamics. The device reproduces neuron‐like integration and firing, short‐timescale associative learning, temporal ECG pattern classification, and nociceptive responses to electrical ...
