Inkjet-Printed, Flexible Organic Electrochemical Transistors for High-Performance Electrocorticography Recordings.

ABSTRACT: Organic electrochemical transistors (OECTs) have emerged as powerful tools for biosignal amplification, including electrocorticography (ECoG). However, their widespread application has been limited by the complexities associated with existing fabrication techniques, restricting accessibility and scalability. Here, we introduce a novel all-planar, all-printed high-performance OECT device that significantly enhances the accuracy and sensitivity of ECoG recordings. Achieved through an innovative three-step drop-on-demand inkjet printing process on flexible substrates, our device offers a rapid response time of 0.5 ms, a compact channel area of 1950 μm², and is characterized by a transconductance of 11 mS. This process not only simplifies integration but also reduces costs. Our opti
