Microelectronics Research Unit is part of the Faculty of Information Technology and Electrical Engineering. Our research is focused electronics materials and their applications. The research facilities of the units can roughly be divided into materials synthesis, fabrication and other facilities. Synthesis facilities is performed in our chemistry laboratory (nano/macro materials, composites), fabrication covers ink and paste formulations and screen/gravure/inkjet printers and other wide variety of characterization tools. The characterization tools include full setup of equipment for piezoelectric poling, optical and electrical (frequency up to 67 GHz) characterization, reliability testing and multiphysic modelling of devices.

Provides facilities and expertise for printing and surface engineering in support for interdisciplinary research and education activities within the Technologies for a Sustainable Future as well as the Solutions for Health profiling areas at Åbo Akademi University. The ÅAFPC instrumentation enables batch and continuous roll-to-roll deposition of functional materials with 2D printers, additive manufacturing and bioprinting with 3D printers, and uniform and patterned surface creation with thin film coating apparatus. The printing and coating technologies are supported by instrumentation for rheological and surface characterization of functional materials.
End-use applications targeted by the researchers utilizing the ÅAFPC facilities range from diagnostic systems, sensors and microfluidic devices to 3D-printed scaffolds for tissue engineering and personalized drug dosage applications.
