Abstract

Synaptic transistors are considered to hold great potential as electronic devices for constructing brain-inspired neuromorphic cognitive systems. Synaptic transistors made of degradable and environmentally friendly materials are a common concern among researchers today. Egg whites are rich in sources and contain abundant hydrophilic functional groups, including –NH and –OH groups, which can facilitate the movement of protons. In this paper, a synaptic transistor using egg white as the gate dielectric for biomimetic simulation and neuromorphic computing is prepared. The fabricated synaptic transistor successfully simulates typical biological synaptic behaviors, such as excitatory postsynaptic current and double-pulse facilitation, and effectively models the transition from short-term memory to long-term memory. Furthermore, based on the long-term memory and conductance linearity of egg-white gated synaptic transistors, it completes the neuromorphic computation for handwritten digit recognition in neural networks, indicating that egg-white gated synaptic transistors have great potential for application in “green” neural-form electronic devices.

基于蛋白作为栅极电介质的突触晶体管的仿生建模和神经计算
突触晶体管被认为是极具潜力的电子设备,可用于构建大脑启发的神经形态认知系统。由可降解和环保材料制成的突触晶体管是当今研究人员普遍关注的问题。蛋清来源丰富,含有丰富的亲水官能团,包括 -NH 和 -OH 基团,可促进质子的运动。本文利用蛋白作为栅电介质,制备了一种用于仿生模拟和神经形态计算的突触晶体管。所制备的突触晶体管成功地模拟了典型的生物突触行为,如兴奋性突触后电流和双脉冲促进,并有效地模拟了从短期记忆到长期记忆的过渡。此外,基于蛋清门控突触晶体管的长期记忆和电导线性,它完成了神经网络中手写数字识别的神经形态计算,表明蛋清门控突触晶体管在 "绿色 "神经形态电子器件中具有巨大的应用潜力。
