Research at MAGLAB covers wide area of topics. We participate in basic research, mostly supported by the Czech Science Foundation, dealing for example with the basic physics oriented to understand the effects which cause trouble in the magnetic sensors, in order to be able to improve them later..
Applied research is oriented generally on the development of specific sensors, their calibration and applications, measurement systems or data processing algorithms. We cooperate with multiple Czech and foreign partners on these projects. Very the often the projects are supported by the Technology Agency of the Czech Republic.
Continually we also do a research requested by our industrial partners, typically from abroad. Recently we worked for instance on these projects: magnetic navigation of drilling heads for vertical and horizontal drilling, ultra-low-noise magnetic sensors for geological prospection, integrated fluxgate sensors or development of ultra-stable current sources for specific calibrations.

Fluxgate effect in thin layers
Project financed by GACR, Grant Agency of Czech Republic (Projekt GA102/08/0743) MAGLAB was developing a new kind of orthogonal fluxgate, employing magnetic microwires as core. On the contrary of classical fluxgate, the output voltage is picked-up at wire’s termination, without need of a pick-up coil. Therefore this sensor is suitable for applications where high miniaturization is required. The working principle of such sensor is based on helicoidal anisotropy induced in the magnetic microwire.
In this picture a microscope photo of magnetic microwire composed by a glass insulated copper core sorrounded by permalloy layer.

Gastric stimulation for obesity treatment & measurement of stomach volume
Cooperation with US team around prof. Jiande Chen, from University of Texas – Medical branch, Division of Gastroenterology. We have developed for them prototype devices and implantable probes for measurement of gastric distention which is supposed to be a switching mechanism for the stimulating implant, that should ensure proper, or better, wanted function of the gastric wall, making the food consumption lower. The distention measurements have been conducted also in vivo on laboratory animals and gave very promissing results.
MPG is a noninvasive diagnostic method for determining amounts (and possibly distribution) of ferromagnetic dusts in lungs of metal workers (grinders, welders, etc.) Remanent magnetic field of lungs is measured after magnetization of subject in strong DC field.
