Advances in organic transistors for artificial perception applications

The rise of intelligent matter and bioelectronics enables the booming development of perception-functionalized devices to serve as a cutting-edge area. Organic field-effect transistors (OFETs) are considered to be attractive candidates for artificial perception applications not only because of their intrinsic flexibility, biocompatibility and solution processability, but also owning to their unique features in efficient molecule design and diverse interface engineering. In this review, we summarized the recent advances and perspectives for organic transistors toward various artificial perception applications. We first introduce the fundamentals of perception-functionalized OFETs. Thereafter, the recent progress in sensors, synaptic transistors and adaptive devices are overviewed. Moreover, we summarized six strategies towards perception-functionalized OFETs, and finally proposed challenges and opportunities of organic transistors in this flourishing field.
