SUINK

The SUINK project, coordinated by Tekniker and featuring 13 European partners, focuses on the development of stand-alone electrical power systems for a wide range of sensors, particularly in the automotive sector to reduce the use of copper wiring. These systems include vibratory energy recovery systems based on piezoelectricity and supercapacitors. The major innovation relies on the formulation of new conductive, dielectric and piezoelectric bio-based inks for printing processes on flexible bio-based substrates. Three currently confidential proofs of concept have been submitted. IMT Nord Europe is coordinating the development of 100% bio-based vibratory energy recovery systems, based on the principle of resonating beams equipped with piezoelectric stacks. Complex work has begun to define specifications (in collaboration with industrial partners Stellantis and Oribay), develop each element (resonating beam and functional layers in collaboration with Tekiner and Centexbel) based on wide-ranging manufacturing techniques (3D printing, direct ink or extrusion printing) up to their assembly, and final electromechanical characterization of the devices. Finally, special attention is paid to the connection with supercapacitors (in collaboration with TAU) and the recyclability of these systems.
