Indium-Gallium-Zinc-Oxide-Based Photoelectric Neuromorphic Transistors for Spiking Morse Coding

The human brain that relies on neural networks communicated by spikes is featured with ultralow energy consumption, which is more robust and adaptive than any digital system. Inspired by the spiking framework of the brain, spike-based neuromorphic systems have recently inspired intensive attention. Therefore, neuromorphic devices with spike-based synaptic functions are considered as the first step toward this aim. Photoelectric neuromorphic devices are promising candidates for spike-based synapt...     

柔性神经形态晶体管及其仿生感知应用

生物感知系统具有高并行、高容错、自适应和低功耗等独特优点.采用神经形态器件实现生物感知功能的仿生,在脑机接口、智能感知、生物假体等领域具有重大应用前景.与其他神经形态器件相比,多端口神经形态晶体管不仅可以同时实现信号的传输和训练学习,还可以对多路信号进行非线性的时空整合与协同调控.然而,传统刚性神经形态晶体管很难实现弯曲变形以及和人体密切贴合,限制了神经形态器件应用范围.所以,具有良好弯曲特性的柔性神经形态晶体管的研究成为了最近的研究重点.本文首先介绍了多种柔性神经形态晶体管的研究进展,包括器件结构、工作原理和基本功能;另外,本文还将介绍上述柔性神经形态晶体管在仿生感知领域中的应用;最后给出上述研究领域的总结和简单展望.
