Abstract

Printing is a promising technique to fabricate commercial organic electronic devices such as OLED, TFT, solar cells and sensors. In this investigation, we report the application of high volume flexographic printing, which makes low cost and batch production possible. Commercial RFID tags have been printed using metallic inks with organic compounds in the Printing Applications Lab (PAL) at Rochester Institute of Technology (RIT). Polyaniline ink was prepared and printed by flexography in the form of test targets and Interdigitated electrodes (IDE). The conductivity can be controlled by different levels of doping. Furthermore, multiple impression printing was used to print overlapping functional layers to obtain all printed organic electronic devices like chemical vapor and humidity sensors. Optical profilometry and SEM were used to analyze the surface and interface structure. Sensitivity was measured and compared with commercial devices.
