适用于大健康、人工智能大数据医疗等的柔性电子已成为本世纪最重要的技术之一。由于其特殊的机械性能、生物相容性和生物可降解性，茧丝（或 SF，丝素蛋白）在柔性电子/光子学中发挥着关键作用。该综述首先对SF材料的分级介观网络结构进行了研究，并基于丝材料的结构和性能之间的相关性介绍了介观重构、介观掺杂和介观杂化的概念。 SF介观功能化是根据分子间核模板开发的。通过在SF材料的重折叠中实施细观重构和功能化技术，可以实现非凡的性能。依靠这种策略，可以开发专门设计的柔性电子和光子元件。本综述涵盖了基于SF材料/介观功能化的介观柔性电子和光子学的最新理念和技术。由于丝材料具有生物相容性和人体皮肤友好性，SF介观柔性电子/光子元件可应用于可穿戴或植入设备。这些器件适用于人体生理信号和活动传感/监测。在人机交互方面，该设备可用于体内信息传输、计算和存储，具有人工智能与人类智能结合的潜力。

Flexible Meso Electronics and Photonics Based on Cocoon Silk and Applications

Flexible electronics, applicable to enlarged health, AI big data medications, etc., have been one of the most important technologies of this century. Due to its particular mechanical properties, biocompatibility, and biodegradability, cocoon silk (or SF, silk fibroin) plays a key role in flexible electronics/photonics. The review begins with an examination of the hierarchical meso network structures of SF materials and introduces the concepts of meso reconstruction, meso doping, and meso hybridization based on the correlation between the structure and performance of silk materials. The SF meso functionalization was developed according to intermolecular nuclear templating. By implementation of the techniques of meso reconstruction and functionalization in the refolding of SF materials, extraordinary performance can be achieved. Relying on this strategy, particularly designed flexible electronic and photonic components can be developed. This review covers the latest ideas and technologies of meso flexible electronics and photonics based on SF materials/meso functionalization. As silk materials are biocompatible and human skin-friendly, SF meso flexible electronic/photonic components can be applied to wearable or implanted devices. These devices are applicable in human physiological signals and activities sensing/monitoring. In the case of human–machine interaction, the devices can be applicable in in-body information transmission, computation, and storage, with the potential for the combination of artificial intelligence and human intelligence.
