Signal of heartbeats – laboratory tool
 Vyplel, Vojtěch ; Vychodil, Josef (referee) ; Sigmund, Milan (advisor)
This work deals with the development of a laboratory device for measuring heart rate. The work will describe the basic anatomy of the heart and the origin of heartbeats. There are also methods for measuring heart rate. A sensor for sensing a heart rate in a laboratory device is described in detail. The work presents the circuit solution of the laboratory device and measurement of its functionality. Furthermore, the work describes the application for the evaluation of heart rate and written instructions for laboratory exercises.

Organic matter impedance extraction and modeling
 Vyplel, Vojtěch ; Balada, Radek (referee) ; Šotner, Roman (advisor)
This thesis addresses the problem of extracting impedance characteristics from organic materials. The aim was to explain the modelling of impedance characteristics using non-integer models of electronic circuits. Also to explain the principle of electro impedance spectroscopy, what is a constant phase element and the Cole model. Based on this knowledge, impedance characteristics were measured and analyzed and circuit models were developed. The resulting measured data are confronted with the theoretical knowledge.
