Nonlinear Energy Harvesting Devices
 Rubeš, Ondřej ; Singule, Vladislav (referee) ; Maga, Dušan (referee) ; Hadaš, Zdeněk (advisor)
This thesis is focused on vibration energy harvester, which is a device converting kinetic energy of vibrations into electrical energy. The approximate dimensions of the device are ten centimeters, and the output power is in milliwatts. A device that generates such amount of power can function as a power source for communication modules and can be used for wireless sensors, which can be utilized for example in the Internet of Things. Existing devices are based on a simple linear oscillator, but they have a narrow operating frequency bandwidth, where they can operate effectively. The bandwidth extension of vibration energy harvesters using nonlinear characteristics is the main aim of this thesis. It leads to a design of a nonlinear device with wide operating frequency bandwidth that provides higher implementation in industry.
