Inkjet-Printed Nafion Gated Graphene Field-Effect Transistors for Bioelectronic Applications

Inkjet printing technology has emerged as a promising tool for fabricating bioelectronic devices, offering scalability and accessibility in device manufacturing processes. In this study, we explore the application of inkjet-printed Nafion-gated graphene field-effect transistors (NF-GFETs) for bioelectronics applications. With the exceptional conductivity and biocompatibility of Nafion, NF-GFETs serve as ion-to-electron transducers, enabling precise control over electronic signals and ion transport. We extend our investigation to encompass varying relative humidity levels, mirroring biological conditions, and demonstrate enhanced device performance under humid environments.
