有机电化学晶体管（OECTs）由于其高介电常数、直接离子-电子耦合和独特的形状因子而作为生物电子应用的潜在通用平台而复兴。这种对生物电子学的感知适用性可以归因于有机混合导体的掺入，其促进离子和电子传输，使得材料固有的从生物信号到非生物读数的转换成为可能。在过去的十年中，多个合成突破已经产生了通道材料，其表现出显着的空穴/电子传输，同时在水性介质中显示电活性。然而，OECT作为生物电子器件的基本原理中隐含的是，它们可以被制造成与生物系统机械兼容，即使可变形OECT的统一指南仍不清楚。在这个角度来看，我们强调最近的进展赋予变形性。具体而言，材料的选择，设计和化学的晶体管的组成部分-基板，电解质，互连，和（聚合物）通道材料-将讨论的背景下，选择生物电子学应用的基准设置。最后，我们确定了未来研究的关键领域，机械兼容的OECTs。
Organic electrochemical transistors (OECTs) have been revived as potentially versatile platforms for bioelectronic applications due to their high transconductance, direct ionic-electronic coupling, and unique form factors. This perceived applicability to bioelectronics can be attributed to the incorporation of organic mixed conductors that facilitate both ionic and electronic transport, enabling material-inherent translation from biological signals to abiotic readouts. In the past decade, multiple synthetic breakthroughs have yielded channel materials that exhibit significant hole/electron transport while displaying electroactivity in aqueous media. Yet, implicit in the rationale of OECTs as bioelectronic devices is they can be fabricated to be mechanically compatible with biological systems, even though unified guidelines for deformable OECTs remain unclear. In this Perspective, we highlight recent advances for imparting deformability. Specifically, materials selection, design, and chemistry for integral parts of the transistor - substrate, electrolyte, interconnects, and (polymeric) channel materials-will be discussed in the context of benchmarks set by select bioelectronics applications. We conclude by identifying key areas for future research towards mechanically compliant OECTs.
