Fiber-Shaped Optoelectronic Synaptic Device for Neuromorphic Computing in Electronic Textiles

Neuromorphic computing shows prospects in the field of wearable electronics due to its significant advantages in edge computing. Fiber-shaped devices represent an optimal platform for wearable systems owing to their weaveability. In this work, we demonstrate a two-terminal optoelectronic synaptic device based on IGZO thin films fabricated on Pt fibers. The top electrode was patterned through a special patternization process and fabricated into a two-terminal device, enabling dual-mode optical/electrical neuromorphic functionalities. Based on of long-term potentiation characteristic, the device achieves 92.1% accuracy on MNIST pattern recognition tasks. These results demonstrate viable approaches for functional diversification of fiber-shaped devices.
