The EMPART research group is a multidisciplinary research unit. Its main activities lie in the electronics materials and devices, and nanotechnology focus areas of the University of Oulu. The group is a key player in the Micro- and Nanotechnology Centre of the University of Oulu, where our overall target is to integrate nanostructures enabling novel functionality of electronic, telecommunication, bio/medical and energy/environmental devices.

The group comprises of specialists in microelectronics, materials, mechanical engineering, measuring techniques, and also in chemistry and physics. The personnel consists of six professors, ten post-doctoral researchers and 15 doctoral students.

The group was funded in 2011 by the University of Oulu, Tekes, EU, Academy of Finland, Nordic Innovation Centre, Scientific Advisory Board for Defense and by domestic and foreign industry. Global research co-operation is a characteristic feature of the EMPART group, having key roles in several EU and other international projects.

In accordance with the long term research targets, we have continued the integration of interdisciplinary topics towards future advanced device and component implementations. In addition, a wide range of application areas utilizing the generic materials knowledge of the group has had great importance from the application point of view.

The group co-operated in 2011 with other Infotech Oulu research groups, being a partner in PrintoCent (Printed Electronics and Optical Measurements Innovation Center) having a printed electronics laboratory. National and international research co-operation included shared projects and publications, and student, researcher and lecturer exchange. The group also acknowledges Finnish and foreign industrial partners for their active participation in research projects.

Materials, components and technologies developed by the group are widely applied in the electronics industry, especially in wireless telecommunication, sensors/actuators and hybrid microelectronics technology. LTCC micromodules and printed electronics devices are important examples of present exploitation, together with recent scientific achievements of nanotechnology with applications. Novel materials, as well as progress in fabrication have been utilized in antennas, sensors, ceramic/polymer integrations, filters, micro-pumps, lens and mirror positioning systems, energy harvesters, optical waveguides etc. The amount of scientific refereed journal publications numbered about 40.
