Scope of activities:

The Institute of Electronics develops research in the field of industrial and biomedical applications of IR thermography. The work focuses mainly on the study of thermal phenomena occurring in electronic systems and energy systems, thermovision nondestructive testing, optical detection of gas leaks using the developed cameras as well as thermal imaging systems, and research in the field of multispectral thermography. These studies are carried out in cooperation with the industrial partners and other research centers.

In addition, research and implementation of new methods and systems of medical thermography for diagnostics and screening are carried out. The research concerns new methods of image processing, in particular for applications in active dynamic thermography. The results of scientific work are new tools, systems and software, mainly for screening using the thermal stress method. An important area of research is thermal modeling of multilayer structures, including tissues, taking into account blood flow, anisotropy, modeling of thin and porous materials and non-Fourier heat transfer.

Possible applications of the research results:

  1. measurements of temperature, current and power of energy systems in varying environmental conditions
  2. fiber optic systems for temperature and stress measurement (Raman spectroscopy),
  3. systems of non-destructive testing of industrial objects - detection of delamination and damage, assessment of the condition of machines and devices, prediction of failures,
  4. IR imaging systems for detecting people and objects in hazardous and explosive environments,
  5. spectrometric systems for measuring the concentration of gases in industrial atmospheres, the composition of steel slag and the content of composite materials.

 

Present activities:

Measurements and spectral analysis of infrared radiation enables testing the properties of industrial objects. The research concerns the development of new methods of measuring radiation intensity and temperature with high sensitivity microbolometric sensors in the range of MWIR and LWIR 3-20 μm and InGaAs detectors in the range of NIR and SWIR 1-3 μm. The developed prototypes of measurement systems and software enable the implementation of new solutions. Innovative technical solutions are patented. The results of the research are new methods and prototype measurement systems for measuring temperature in industrial conditions, in an explosive atmosphere, systems for detecting defects, assessing the condition of machines, for measuring stresses, atmosphere composition, for detecting people and other objects in foggy, smoky atmospher and in the presence of poisonous and explosive gases.

Scope of activities:

Wireless systems operating in the proximity of human body (the so-called Wireless Body Area Networks - WBANs) enable the transfer of data between devices placed close to the body. They include a wide variety of solutions, from the most popular, commonly used, for example, for monitoring the course of training by people practicing sports, to specialized diagnostic systems used in medicine. Research work on such systems covers many aspects. These include the development of physical and numerical models of the human body to determine the impact of electromagnetic waves on the body as well as human influence on the functioning of the wireless system. In addition, the research also concerns the optimization of the topology of such systems by the selection of the number of system nodes and their spatial arrangement. In the case of such systems, it is also important to design wearable antennas that can function properly being placed close to the human body.
