Organic Electrochemical Transistors Monolithically Integrated with Precise Micro-Dispensing Enable High-Performance Biosignals Amplification.

ABSTRACT: Organic electrochemical transistors (OECTs) are key components in advanced bioelectronics, wearable devices, and neuromorphic biointerfaces. However, to fully unlock their potential and facilitate widespread adoption, the development of high-performance OECTs and their seamless integration into circuits is essential, yet still limited. In this work, the monolithic integration of OECTs and OECT-based amplifiers, fabricated entirely on flexible substrates using high-resolution micro-dispensing, is reported. This additive method enables precise deposition of conductors, semiconductors, insulators, and electrolytes across a wide viscosity range (10 -10⁵ cP) with micrometer-scale resolution and femtoliter-volume control. The resulting transistors achieve a record intrinsic gain of 33
