Communication Systems (ComSys) Research Group

Measurement Electronics Research Group of Thomas Johann Seebeck Department of Electronics at Tallinn University of Technology (TalTech) performs R&D on various test, measurement and data acquisition solutions.
The research team has long-term experience in developing impedance spectroscopy-based measurement solutions for medical / healthcare as well as materials science, industry and other applications. The history of impedance measurement at the University of Technology dates back to the 1930s (Paul Plakk's work on the applications of physical chemistry) and the 1980s (vector voltmeters - Mart Min, Toomas Parve).

The research group has been engaged also in the R&D of solutions based on image processing (3D laser scanners, medical image processing with machine learning – O.Märtens - in cooperation with doctoral students (Tõnis Saar, Ago Mõlder, Anindya Gupta and others).

The members of the research group are the authors of hundreds of scientific articles, dozens of book chapters and tens of inventions.

Key Persons:

  • Prof Olev Märtens - signal processing, eddy current (magnetic induction) based resistance, image processing, remote sensing;
  • Dr Paul Annus - data acquisition, sampling theory and applications, philosophical questions of impedance,
  • Dr. Raul Land - experiments and interpretation of impedance
  • Dr Jaan Ojarand - impedance in microfluidics, medical inductive and other applications
  • Prof Mart Min - public relations, patenting, cooperation with international communities (ICEBI, IEEE EMBS and IMS, etc.)
