Transparent, conductive and flexible electrodes are one of the most important components of the development and design of new consumer electronics for everyday use. Currently, such electrodes are based on expensive metals such as indium, which is one of the more rare metals in the earth's crust. Manufacturing is also done at high cost and with advanced technology. The project proposes technologies for developing flexible, transparent and conductive electrodes based on integrated metallic carbon nanotubes, functionalized graphs and abundant metals. The goal is that the electrodes should be able to manufacture with scalable processes, such as spray coating, or so-called scroll-to-roll printing.
Research Seminar and Programme planning on Transparent, conducting and flexible films for electrodes, June 3 and 4, 2019, Oulu. The goal of the event is to disseminate our results and to initiate newer and tie the existing collaboration with companies stronger. The event also gives us the opportunity to oversee funding instruments (e.g. H2020, Euripides, Business Finland, M-era.Net) and to plan future projects.
Research on devices that are entirely printed (including substrate, electrode and functional material) are agreed with researchers at VTT Technical Research Centre of Finland.
