Key enablers and scientific breakthroughs
Through theoretical modeling and simulation, we have discovered new efficient materials in the THz region, whose responses are easily and dynamically adjustable to different wavelengths.
We are able to manufacture quantum dot based heat detectors using printing techniques, which has decreased their manufacturing costs. Our unit has the ability to design and manufacture a variety of different sensor and detector elements, thus enabling the construction of key new types of measurement systems.
The measurement technique is based on the analysis of plasma generated by electric discharge. The technology enables online measurement of water quality, and has been commercialized by the unit’s researchers (Sensmet Oy).
We were the first in the world to measure both blood pressure and signals of the heart and circulatory system simultaneously in a brain imaging environment. Multimodal measurement is based on the utilization of magnetoencephalography, magnetic resonance imaging and magnetic resonance encephalography.
A diagnostic tool for detecting early-stage changes in the peripheral circulation of humans as a result of diabetes. The collagen structure of the skin changes due to the effects of diabetes, and it can be observed as a change in the polarization index when the skin is imaged over a wide wavelength range.
An innovation made by our unit; a quality control method based on electrical induction and thermal imaging, which is able to measure, for example, the uniformity of electronic materials, and thus provide important information about the electronics manufacturing process. The same method can also be used to identify, for example, the location of a fault in a solar panel. Work on the commercialization of this technology is underway.
