摘要
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.
