Organic Mixed Ionic-Electronic Conductors for Low-Power Electronics

Organic mixed ionic-electronic conductors (OMIECs) are versatile materials widely used in fields such as bioelectronics, optoelectronics, and energy storage due to their unique ability to transport both ionic and electronic charges efficiently. This sets them apart from other organic semiconductors and enables innovative signal transduction approaches. OMIECs are commonly employed in organic electrochemical transistors (OECTs), where ion-modulated doping and dedoping lead to significant changes in channel conductance, resulting in low operating voltage, high transconductance, and compatibility with biological systems. In this presentation, we will provide an overview of our efforts to create OMIECs that can be processed using environmentally friendly solvents, such as alcohol or water. We will explore the application of these formulations in the fabrication of energy harvesting devices and ultra-low-power complementary electronic circuits. Additionally, we will discuss the utilization of screen and 3D printing techniques for high-throughput screening of new materials and device concepts, demonstrating their effectiveness in developing energy-efficient bio-inspired organic electrochemical devices and circuits. This advancement holds the potential to significantly contribute to the widespread adoption and sustainable integration of organic electronics in various commercial applications.
