Abstract In the natural world, human brain is most powerful information processor, using a highly parallel, efficient, fault‐tolerant, and reconfigurable neural network. Taking inspiration from this impressive architecture, optoelectronic synaptic devices have gained considerable attention for their ability to process retain data simultaneously, making them essential components in upcoming era of neuromorphic computing systems. recent years, significant progress has been made development two‐dimensional (2D) material heterostructures. This review focuses on use 2D materials creating devices. It discusses utilizing heterostructures these examines potential different areas such as image recognition, wearable electronics, logical operations, Heterostructures with provide wide range possibilities electronic band structures can be easily tailored achieve effective optical electrical modulation. Optoelectronic based simultaneously exhibit two functionalities: detection memory. Furthermore, strong interatomic bonding within layers possess thickness only one atomic layer, giving exceptional flexibility, transparency, mechanical strength. By solution processing ultra‐thin profile, manufacturing three‐terminal synapses becomes cost‐effective, simplifying integration processes.
