摘要:

水凝胶力学性质与生物组织相似,生物相容性好,在生物电子学领域具有独特的优势。受生物组织——如皮肤、神经、肌肉等启发,发展了具有仿生结构和功能的水凝胶材料。以这种水凝胶材料制作而成的柔性电子器件具有感知温度、压力、应变、电场等外界刺激的功能,可模拟生物组织的传感能力,在仿生电子皮肤,人工肌肉,人工神经等领域具有重要的应用前景。总结了水凝胶仿生柔性电子学的研究进展,包括水凝胶柔性电子器件,水凝胶仿生柔性电子学的应用以及目前面临的主要挑战,并对未来需要解决的科学问题和发展方向进行了展望。

Abstract:

Hydrogels have tissue-like mechanical properties and excellent biocompatibility, and are widely recognized as ideal candidate materials for bioelectronics. Inspired by bio-tissues such as skin, nerves, and muscles, etc., a lot of hydrogels with biomimetic structures and functions have been developed to mimic the capability of creatures to sense external stimuli including temperature, pressure, strain, and electric field, etc. Such biomimetic hydrogels have important applications in electronic skin, artificial muscles, and artificial nerves, etc. This article reviews recent progress of biomimetic flexible hydrogel electronics, including representative hydrogel flexible electronic devices, typical applications, and major challenges in this field. Some open key scientific issue and important directions are outlooked in a brief perspective section at the end.

Key words: Hydrogel, Flexible electronics, Biomimetics, Electronic skin
