At the Laboratory for Microsensor Structures and Electronics we focus our research on advanced microfluidic systems. We are experts in development of micropumps, biological and catalytic microreactors, microneedle systems for medical applications, microdosing wearable systems for controlled drug administration, Lab-on-a-chip systems, micromixers, and microfluidic droplet generators. Recently we developed new types of piezoelectric micropumps (mikrocylinderTM pump) which enable bi-directional pumping, electrically controlled valve regime and bio-mode operation.

We also design and fabricate microreactors and lab-on-a-chip systems which can be optimized for a specific use and usually consist microfluidic elements such as mixers, separators, tanks, inlets, and outlets etc.

Another focus of ours is microfluidic devices with medical applications. For example, arrays of microneedles can be used in place of conventional drug administration into the tissues. Needles typically penetrate only 100 – 200 µm deep and the process in painless. Another potential use of microfluidics can be seen in wearable microdosing systems for controlled drug admission. These systems consist of microneedle arrays, micropump with corresponding controllers and an integrated microprocessor.

Our technologies have potential applications in chemical and biochemical field, point-of-care testing, diagnostic tests, drug discovery, chemical engineering ect.
