Polymer synaptic transistors from memory to neuromorphic computing

Recent developments in the state-of-the-art optoelectronic synaptic devices based on 2D materials: a review

“…88 Similar to the variety of stimuli influencing biological synapses, synaptic devices can also be triggered by several kinds of input signals, such as electrical pulses (varying magnitude, frequency, and duration of voltage pulses, including specific voltage patterns), photonic pulses (modulating amplitude and wavelength), chemical stimulus (using specific molecules or ions), etc., depending on the particular design and functionalities of the devices. 18,19,76,[89][90][91] The synergy between the electronic and photonic stimuli in synaptic devices enhances their capabilities in terms of speed, efficiency, adaptability, and parallelism. In particular, the research on optoelectronic synaptic devices to create artificial synapses is focused primarily on novel materials and device architectures.…”

Optical Memory, Switching, and Neuromorphic Functionality in Metal Halide Perovskite Materials and Devices

“…An overview of various synaptic functionalities could be found in the references. [29,56] Although most examples of memory functionality (learning and forgetting) have been demonstrated using electrically stimulated devices, an interesting prospect is the realization of optical neuromorphic memory and neural emulation (Figure 2c). Several studies have shown that both memory and forgetting can be stimulated by pulse trains, with the efficacy (memory level and retention time) correlated with the intensity, duration, and quantity of the pulses.…”

Novel Application of Phosphorescent Material for Non‐Volatile Flash Photomemory and Artificial Photonic Synapse

“…2022, 32, 2206040 the brain is seen as a highly attractive topic for the application of in-memory computing. [56][57][58][59][60][61] The behavior of floating-gate photomemory actually is similar to the synaptic transmission process, where the transmission will take place as there is an action potential triggered by a light signal. When the light signal is received, the neurotransmitter will be released from the pre-synaptic neuron, cross the synaptic cleft, and then received by the post-synaptic neuron.…”
