ABSTRACT: The field of organic electronics holds tremendous potential for applications that benefit from the use of organic materials, e.g. very low cost, flexible and amendable to large-area processing techniques or roll-to-roll printing. Specifically, the design and development of sensors that take advantage of these benefits can lead to manufacturing of cheap electronic units for electronic skin as well as medicinal, food storage, and environmental monitoring applications. The ability to couple the sensory electrical output with on-chip signal processing can overcome the need for bulky, expensive equipment typically required for most optical detection methods. In order to attain commercial viability, chemical sensors based on organic electronics must continue to address the remaining issues in repeatability, reproducibility, stability, and selectivity. In this talk, I will present recent progress in materials and fabrication of chemical, biological and pressure sensors.
