SOrganic bioelectronic devices bridge the gap between electronic signal processing and ionic communication in biological environments. Among them, Organic Electrochemical Transistors (OECTs) have attracted particular attention for biosensing applications due to their low operating voltage, high energy efficiency, and excellent stability in aqueous environments. After gaining a deep understanding of what governs the operating mechanism of the OECT device, specifically what affects the threshold voltage (Vth) of the device, this work introduces a straightforward and energy-efficient strategy to integrate multiple bio-responsive functionalities into a single electrolyte-based transistor. The blending approach, whether combining two Organic Mixed Ionic-Electronic Conductors (OMIECs) or an OMIEC with a non-OMIEC semiconducting polymer, allows precise control over the microstructure through composition and processing, yielding device properties unattainable with single-material systems.
