As an Early Stage Researcher at RISE, I intend to evaluate different printing techniques (including inkjet printing, screen printing, gravure printing and aerosol jet printing) for the manufacturing of organic electrochemical transistors (OECTs) and electrolyte-gated organic field-effect transistors (EGOFETs) on different substrates. Printed transistors based on organic materials will be employed in biosensing applications for the detection of various chemical substances, etc.
Fabrication of OECTs and EGOFETs, by using various printing techniques, will generate knowledge and requirements of materials, ink formulations and device structures, all aiming at an optimized manufacturing process. A variety of manufacturing methods will give a certain degree of freedom in terms of different device designs and architectures as well as materials with different physical, electrical, and chemical properties. The fabricated organic transistors will be characterized in order to understand the impact on the switching behavior when varying e.g. device dimensions and manufacturing processes. Knowledge of key features of each fabrication method will open pathways towards rational manufacturing strategies and integration.
Fabrication and development of OECTs and EGOFETs is currently ongoing at the Printed Electronics Arena (PEA; www.printedelectronicsarena.com) in Norrköping, Sweden, an innovation cluster and ecosystem for research and development in printed electronics.
The research activities are carried out within the BORGES project, funded under H2020-EU.1.3.1, grant agreement ID: 813863.
