摘要:

近年来, 受人脑独特工作模式的启发, 利用人工神经形态器件模拟突触和神经元的感知与计算功能吸引了广泛关注。到目前为止, 已经有很多关于神经形态晶体管的报道, 但绝大多数器件是在刚性衬底上加工的。柔性神经形态晶体管不仅可以同时实现信号传输和训练学习, 对多路信号进行非线性的时空整合与协同调控, 而且能密切贴合柔软的人体皮肤, 承受器官和组织的高生理应变。更重要的是, 柔性神经形态晶体管具有可设计的灵活性和优异的生物兼容性, 在检测生物环境中生理相关时间尺度的低幅信号方面具备独特的优势和应用潜力。柔性神经形态晶体管已经广泛应用于电子皮肤、人工视觉系统、智能可穿戴系统等领域。目前, 研制低功耗、高密度集成的柔性神经形态晶体管是研究的首要任务之一。本文综述了基于不同柔性衬底的神经形态晶体管的研究进展, 并展望了柔性神经形态晶体管的未来应用前景,这将为未来柔性神经晶体管的研制以及智能计算和感知应用提供比较详实的参考。

Abstract:

In recent years, inspired by the unique operation mode of the human brain, emulation of the perception and computing functions of synapses and neurons by artificial neuromorphic devices has attracted more and more attention. So far, many researches have been reported about neuromorphic transistors (NMT), but most devices are fabricated on rigid substrates. The flexible neuromorphic transistors can not only realize signal transmission and training learning at the same time, but also carry out nonlinear spatio-temporal integration and cooperative regulation of multiple signals. It can also closely fit the soft human skin and withstand the high physiological strain of organs and tissues. More importantly, flexible neuromorphic transistors have unique advantages and application potential in detecting low amplitude signals at physiologically relevant time scales in biological environments due to their designable flexibility and excellent biocompatibility. Flexible neuromorphic transistors have been widely used in electronic skin, artificial vision system, intelligent wearable system, and other fields. At present, it is one of the most important tasks to develop low-power consumption, high-density integrated flexible neuromorphic transistors. In this paper, the research progress of NMT based on different flexible substrates is reviewed. In addition, the bright application prospect of flexible neuromorphic transistors is prospected. This review provides a reference for the development and application of flexible neuromorphic transistors in the future.
