Abstract

Temperature is always one of the most important factors that critically affects the electrical performance of devices. In the present work, the thermochromic function has been realized on oxide neuromorphic transistors gated by a chitosan based electrolyte mixed with temperature-sensitive thermochromic powder. Except for extremely strong proton gating effects, the device exhibits temperature-sensitive thermochromic activities with good electrical performance. It also demonstrates typical synaptic functions at different temperatures, mimicking heat pain sensation activities. Additionally, a high recognition accuracy of ∼93.80% for MNIST handwritten digits is obtained at different temperatures, indicating good stabilities for neuromorphic computing. The present work opens up interesting idea for bionic cognitive electronic skin and bionic thermochromic cognitive platforms.

具有温度敏感热致变色功能的质子门控氧化物神经形态晶体管

温度始终是影响器件电气性能的最重要因素之一。在本研究中，我们在氧化物神经形态晶体管上实现了热致变色功能，该晶体管由基于壳聚糖的电解质与对温度敏感的热致变色粉末混合而成。除了极强的质子门控效应外，该器件还表现出对温度敏感的热致变色活动和良好的电气性能。它还能在不同温度下显示典型的突触功能，模拟热痛觉活动。此外，在不同温度下，MNIST 手写数字的识别准确率高达 93.80%，表明神经形态计算具有良好的稳定性。本研究为仿生认知电子皮肤和仿生热变色认知平台开辟了有趣的思路。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
