The system of load matching to the energy converter
Halama, Petr ; Mandlík, Michal (referee) ; Drexler, Petr (advisor)
This master’s thesis deals with energy harvesting from the mechanical energy sources. The mechanical energy may be converted into the electrical by means of a vibrational microgenerator. The thesis deals also with the production of energy from different renewable sources. There have been identified conditions for effective transformation of the remaining energy. In order to satisfy these conditions a circuit for load matching to energy harvester has to be used. Four variants of matching circuit have been designed and analyzed in PSpice or LTspice. It has been designed a system of power factor correction controlled by circuit with discrete components and also by microcontroller. For one of these variants a specific integrated circuit has been used. The designed circuits have been built and their parameters haven been determined by measurement.

Dielectric Elastomers
Fiala, Vojtěch ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The thesis contains extensive theoretical information and consist of several parts, where in the first part of the text are specified mainly general knowledges about electroactive polymers (EAP) and their different types. In this part, the reader should get a basic view of the issues and realize sense of these materials. The following text is more specifically addressed on one group of electrical EAPs called dielectric elastomers (DE). Introduction to DE is conceived comprehensively, that means from general information and principles of function to specific and deeper information. For example in the text are included information about individual materials and differences between them, particular application areas, etc. Above all, the text focuses on the fields of sensorics and energy generation.

Thermoelectric Generator
Štetina, Jakub ; Ančík, Zdeněk (referee) ; Vlach, Radek (advisor)
This thesis describes measuring of thermoelectric modules and building of the device, which would serve as an emergency electric energy source for specific purpose on the basis of ther-moelectric effects. We use thermoelectric generators (TEG).
