自 20 世纪 70 年代发现导电聚乙炔以来，本征导电聚合物 (ICP) 因其有趣的结构、性能和应用而引起了极大的关注。与金属和掺杂半导体等传统导体显着不同，ICP 具有高机械灵活性且重量轻。此外，它们的性能可以通过控制掺杂水平、改变化学结构或与有机或无机材料形成复合材料来轻松调节。它们在生物电子学中的应用特别有趣，因为它们具有良好的生物相容性以及与生物组织良好的机械匹配。在本文中，首先回顾了提高 ICP 机械拉伸性的方法，因为生物电子应用通常需要高拉伸性，而原始 ICP 的拉伸性通常有限。讨论了 ICP 作为可拉伸电极在表皮生物电检测和神经接口中的应用。然后，回顾了 ICP 作为机械传感器的电极或传感材料的应用。它们在可控药物输送方面也有重要应用。最后，还涵盖了它们在可穿戴能量收集和存储设备（包括热电发电机和超级电容器）中的应用。回顾了 ICP 作为机械传感器的电极或传感材料的应用。它们在可控药物输送方面也有重要应用。最后，还涵盖了它们在可穿戴能量收集和存储设备（包括热电发电机和超级电容器）中的应用。回顾了 ICP 作为机械传感器的电极或传感材料的应用。它们在可控药物输送方面也有重要应用。最后，还涵盖了它们在可穿戴能量收集和存储设备（包括热电发电机和超级电容器）中的应用。

Bioelectronic Applications of Intrinsically Conductive Polymers

Since the discovery of conducting polyacetylene in the 1970s, intrinsically conducting polymers (ICPs) have attracted great attention because of their interesting structure, properties, and applications. Notably different from conventional conductors such as metals and doped semiconductors, ICPs have high mechanical flexibility and are light weight. In addition, their properties can be easily tuned by controlling the doping level, modifying the chemical structure, or forming composites with organic or inorganic materials. Their application in bioelectronics is particularly interesting because they have good biocompatibility and good mechanical matching with biological tissues. In this article, the methods to increase the mechanical stretchability of ICPs are first reviewed because high stretchability is often required for bioelectronic applications while pristine ICPs generally have limited stretchability. The application of ICPs as stretchable electrodes for epidermal biopotential detection and neural interfaces is discussed. Then, the employment of ICPs as the electrodes or sensing material of mechanical sensors is reviewed. They also have important application in controllable drug delivery. Last, their applications in the wearable energy harvesting and storage devices including thermoelectric generators and supercapacitors are also covered.
