Energy Harvesting for Automotive Applications
Novotný, Jan ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
This thesis goal is to get information about Energy Harvesting and subsequent confrontation of it. The Energy Harvesting technology deals with process of absorption so-called free energy and conversion it into electric energy. The reason for doing that is mostly feeding wireless sensors. When the search in this area is accomplished on bases of existing constructional principles the concrete device (generator) is designed. This system might be unlimited power source for selected automotive application.

Study of Electromechanical Power Generator for Energy Harvesting Use
Adámek, Pavel ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
This work deals with complex information about state-of-the-art harvesting electric energy from mechanical energy. Particular constructional and physical principles of electromechanical conversion are shown. Further, it presents a proposal of generator, which the owner would be able to carry always without being troubled by it (e.g. generator electric energy in shoe) and which would feed energetically simple devices.

Study of Energy Harvesting in Aeronautic Applications
Březina, Martin ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
Motivation of this study was to clarify the possible solutions to reduce the number of general aircraft security controls with keeping the required safety of flight operations. Among the appropriate approach to solving the problem seems to be the use of energy harvesting devices to power wireless monitoring system of aircraft structures during their operation. The work deals with the various alternatives of using the ambient energy available in the general air transport and processing methods. The study also includes the selection of a particular type of processing available ambient energy and determination of parameters of selected energy-harvesting generator using simulation modeling and performance to meet the power requirements of monitoring system sensors.

Test of Vibration Power Generator with Longitudinal Coil
Stejskal, Jan ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with activation and testing of Vibration Power Generator with Longitudinal Coil which was designed at Brno University of Technology. One of goals of the thesis is to compile simulating model of this device and to compare its results with data gained from measuring device used while testing on the vibration stand. This Vibration Power Generator could be theoretically used in aerospace industry as well as in other branches of industry. It´s important to minimalize its dimensions and weight as much as possible. On the other hand, there are some parameters which should stay unchanged with respect to troublefree work of the device. According to those facts, some changes of construction were proposed within this thesis.

Shock Absorber for Generating of Electrical Energy
Maťaš, Marek ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This these is considering with possibilities of generation of electric energy, with use of linear generator in automotive industry, that linear generator is replacing shock absorber. Subsequently the base model of shock absorber is used and excited with sinus signal. From this simulations are got the results of damping and power. Then it will be made a simulation of shock absorber, with known parameters of damping, mass of vehicle and real model of road. Then it is made control with PID regulator.
