Healthcare Monitoring Sensors Based on Organic Transistors: Surface/interface Strategy And Performance

Organic transistors possess inherent advantages such as flexibility, biocompatibility, customizable chemical structures, solution?processability, and amplifying capabilities, making them highly promising for portable healthcare sensor applications. Through convenient and diverse modifications at the material and device surfaces or interfaces, organic transistors allow for a wide range of sensor applications spanning from chemical and biological to physical sensing. In this comprehensive review, we focus on the surface and interface engineering aspect associated with four types of typical healthcare sensors. We systematically analyze and highlight the device operation principles, sensing mechanisms, and particularly focus on surface/interface functionalization strategies that contribute to the enhancement of sensing performance. An outlook and perspective on the critical issues and challenges in the field of healthcare sensing using organic transistors are provided as well.This article is protected by copyright.
