Ørjan Grøttem Martinsen research is mainly on the passive electrical properties of biological materials (bioimpedance). Since these properties are highly influenced by the anatomy and physiology of the tissue, bioimpedance measurements can be used for characterization or diagnostication of the tissue. It is e.g. possible to use bioimpedance measurements to classify cancerous tissue, to separate between different qualities of meat, to assess the moisture content of the skin or the stress level of a person. These are just a few of numerous possible applications of bioimpedance technology in medicine, biology, sports, cosmetics and psychology. My particular expertise is within bioimpedance basic theory, instrumentation, electrode systems, non-linear phenomena, and modeling.
