SUPERIOT has not only developed key electrical components for future IoT nodes using material-conserving and scalable printing and thin film deposition techniques but also demonstrated the use of novel materials and fabrication processes that enable improved sustainability compared to the state-of-the art in printed electronics. In the future, the printed components can be used to sustainably construct widely scalable IoT sensor nodes for applications where the computational power of conventional Si-based electronics is not needed (i.e. computation is performed in the network side). The components enable light sensing with resistive sensors, simple logic functions with thin film transistors (TFTs), DC rectification with Schottky diodes, energy harvesting with organic photovoltaics (OPV), energy storage with micro supercapacitors ('\u00b5SC), and light and radio communication with OPV and antennas, respectively. The key advances for the components are summarized as follows: i) resistive light sensors using ZnO and perovskites as the active material for UV and visible light inputs; ii) miniaturized TFTs with 5 '\u00b5m channel lengths have been demonstrated using high-resolution printing; iii) Schottky diodes with In-free metal oxide semiconductor for RF operation; iv) OPVs with a material stack optimized for sustainability on sustainable substrate made from regenerated cellulose and coated with a biopolymer coating for improved processability; v) '\u00b5SCs utilizing high surface area 2D-material electrodes and replacing toxic solvents with greener alternatives for the 2D inks; and vi) various thin-film antennas such as thin-film Cu, graphene, and metal mesh depending on the needs of the application (e.g. transparency, quality factor).","references":"Deliverables D2.1., D2.3. and D2.4. outline the developments with printed electronic components in the project and the demonstration of integration of printed components into hybrid and fully printed IoT nodes with energy-harvesting capability. \nRotary-screen printing with improved registration and dimensional stability for flexible electronics\nMarja Va\u00a4lima\u00a4ki, Tuomas Happonen, Toni Karhu, Pekka Ontero, Enni Luoma, Jyrki Ollila, Pentti Korhonen, Antti Takaluoma, Harmen Rooms and Thomas M Kraft, Flexible and Printed Electronics 10, 015003 (2025).\nGreen fabrication of stackable laser-induced graphene micro-supercapacitors under ambient conditions: Towards the design of truly sustainable technological platforms, Sara L.
