Recent progress in using biomaterials to fabricate functional electronics has got growing attention for the new generation of environmentally friendly and biocompatible electronic devices. As a kind of biological material with rich source, proteins are essential natural component of all organisms. At the same time, artificial synaptic devices are of great significance for neuromorphic systems because they can emulate the signal process and memory behaviors of biological synapses. In this report, natural chicken albumen with high proton conductivity was used as the coupling electrolyte film for organic/inorganic hybrid synaptic devices fabrication. Some important synaptic functions including paired-pulse facilitation, dynamic filtering, short-term to long-term memory transition and spatial summation and shunting inhibition were successfully mimicked. Our results are very interesting for biological friendly artificial neuron networks and neuromorphic systems.
利用生物材料制造功能性电子产品的最新进展，已受到新一代环保且生物相容的电子设备越来越多的关注。蛋白质作为一种来源丰富的生物材料，是所有生物体必不可少的天然成分。同时，人工突触器件对于神经形态系统具有重要意义，因为它们可以模拟生物突触的信号处理和记忆行为。在本报告中，具有高质子传导性的天然鸡蛋白被用作制备有机/无机混合突触器件的耦合电解质膜。成功模拟了一些重要的突触功能，包括双脉冲易化、动态滤波、短期到长期记忆转换以及空间总和和分流抑制。我们的结果对于生物友好型人工神经网络和神经形态系统非常有趣。
