Bioartificial Synapses for Neuromorphic Computing

Abstract

As a promising solution for overcoming the bottlenecks of traditional von Neumann computers, the hardware implementation of neuromorphic computing has attracted increasing interest. High-performance artificial synapses are the basic units of brain-like chips and are important for achieving efficient neuromorphic calculations. This paper reports the fabrication of Al/chitosan (CS)/graphene oxide (GO)/indium tin oxide (ITO) artificial synapses. The electronic insulation and proton conduction properties of CS enable it to conduct electricity alone and accelerate the movement of oxygen vacancies in GO. In particular, an experimental device successfully simulated the Pavlov associative memory experiment and was made to exhibit both short-term and long-term memory capabilities by modifying the external stimuli. This device provides a possible avenue to realize neuromorphic engineering on the basis of biomemristors.

Recent progress of organic artificial synapses in biomimetic sensory neural systems

“…47 High-performance This journal is © The Royal Society of Chemistry 2024 organic artificial synapses are essential for efficient neuromorphic computing, flexible robotics, wearable AI systems, and neuromorphic electronics. 48 Compared to inorganic synapses, organic synapses offer the potential to imitate the mechanisms and functionality of biological synapses, including short-term and long-term memory, Hebbian and multimodal learning, and neuromorphic systems, 1 through their molecular diversity, ease of manufacture, excellent optical and chemical properties, and impressive mechanical flexibility. 49 It has been discovered that the energy consumption of organic artificial synapses can be comparable to that of biological synapses (B1-10 fJ per synaptic event).…”

Chiral nematic cellulose nanocrystal composites: An organized review

“…As such, several groups have demonstrated the co-assembly of photo-crosslinkable PEG diacrylate (PEGDA) with CNCs to form chiral nematic films. [84,[178][179][180] Typically, subsequent photopolymerization results in network formation between the incorporated PEGDA chains, yielding stable plasticized films with a much-improved strain at break, and reversible swelling in select solvents. This approach has been successfully applied with several other photopolymerizable systems, predominantly polyacrylamides [181,182] or polyacrylates.…”

“…[21] In contrast, S is a conversiontype material that interconverts with polysulfides in non-aqueous electrolytes offering high theoretical specific capacity (1675 mAh g −1 ), low cost, and environmental friendliness. [22][23][24][25][26][27][28][29] Despite being promising candidates for next-generation rechargeable secondary batteries, Al-S battery (ASB) has not been extensively studied.…”
