Abstract

Organic electrochemical transistors (OECTs), as one of the most promising sensing techniques, have shown various advantages compared to traditional means, which include ultra-high sensitivity, low driving voltage, and excellent biocompatibility for different bioelectrical and biochemical sensing. Moreover, to fully unleash the potential of OECT sensors, integrated sensing systems, especially OECT-based sensing arrays, are widely investigated due to spatiotemporal resolution, mechanical flexibility, high optical transparency, low power dissipation, and ease of fabrication. These advantages are attributed to the unique working mechanism of OECT, novel mixed ionic-electronic (semi)conductors, adaptable device geometry/structure, etc. In this review, advances in OECT-based sensing systems are systematically summarized, with a focus on the OECT-based sensing array. Furthermore, perspectives, concerning stability, cut-off frequency, integrating density, and power dissipation, are discussed based on recent studies on OECTs and their relevant sensor arrays. Last, a summary and an outlook of this field are provided.
基于有机电化学晶体管的集成传感阵列
有机电化学晶体管(OECTs)作为最具发展前景的传感技术之一,与传统传感手段相比,具有超高灵敏度、低驱动电压和优异的生物相容性等优点,可用于不同的生物电和生化传感。此外,为了充分释放OECT传感器的潜力,集成传感系统,特别是基于OECT的传感阵列,由于其时空分辨率,机械灵活性,高光学透明度,低功耗和易于制造而得到广泛研究。这些优势归功于OECT独特的工作机制,新型混合离子-电子(半导体)导体,适应性强的器件几何/结构等。本文系统总结了基于oect传感系统的研究进展,重点介绍了基于oect传感阵列的研究进展。此外,基于oect及其相关传感器阵列的最新研究,讨论了稳定性、截止频率、积分密度和功耗方面的观点。最后,对该领域进行了总结和展望。
