Electrical properties of the skin
Hellová, Miriam ; Čudek, Pavel (referee) ; Špinka, Jiří (advisor)
This work deals with the electrical properties of human skin, the possibilities of measuring its impedance, and the design of suitable electrodes for measurement. Various equivalent circuits for human skin were used, and phenomena that occur at the wet electrode-electrolyte interface, which significantly affect the measurement, were described. A description of the function of a dry planar electrode and its design for verification measurements were performed. Control measurements were performed using a EVAL-AD5933EBZ development kit in a frequency range of 5 kHz to 100 kHz at three different locations on the human body; the results were plotted in the form of the absolute value of the impedance and its phase. The accuracy of the measured values was verified by comparing the results with other works using a different electrode type. The main result of this work was to verify the possibility of using the geometry of a dry planar electrode in combination with an easily accessible evaluation board for simple diagnostic applications.

Revitalization program Cellulite - dermopanniculosis deformans and its verification in practice.
ŠPINDLEROVÁ, Martina
Diploma thesis deals with developing and testing of revitalization program which has positive effect on Cellulite-dermopanniculosis deformans. The research presents and evaluates results of revitalization program which took 6 months. Analysis of technical terms, that are closely related to cellulite, is presented in the theoretical part. There are presented views of Czech and foreign experts who deal with issues of cellulit. At the end of theoretical part we focused on available revitalizing methods that are aiming to elliminate cellulit. Experimental investigation was carried out on 60 women who were divided into experimental and control groups. Results are statisticaly processed in the form of graphs and tables and acompanied with discussion.
