Voltage-dependent time constants for neuromorphic organic electrochemical transistor applications

Abstract

Organic electrochemical transistors (OECTs) with neuromorphic functions were developed using layer-by-layer ferrocene coatings on PEDOT:PSS. The ferrocene unit density increased proportionally with more layers. Neuromorphic behavior, including synapse plasticity, was controlled via gate voltages linked to capacitive or redox processes. This approach offers promising flexibility for programmable neuromorphic device design.
