Abstract

Neuromorphic computing, which mimics the functionality of human neural networks, has gained attention as a next-generation

computing approach due to its advantages in high-speed data processing and low power consumption. As a result,

extensive research has been conducted on synaptic transistors to realize this technology. Among them, electrolyte-gated

organic synaptic transistors (EGOSTs) stand out due to their ability to regulate channel conductivity at ultra-low operating

voltages, making them a crucial component for high-performance neuromorphic hardware. Channel modulation strategies

play an essential role in enhancing synaptic performance by reducing dependence on external factors and enabling precise

conductivity control, which is critical for developing high-performance EGOSTs. This review provides an overview of the

fundamental operating principles of EGOSTs and explores various channel modulation strategies, concluding discussions

on future advancements and technical challenges.
