Vibration Harvester for Aircraft Applications
Rubeš, Ondřej ; Vetiška, Vojtěch (referee) ; Hadaš, Zdeněk (advisor)
This thesis is focused on modification of a design proposal of a vibration energy harvester for autonomous aircraft applications. Vibration energy harvester is mechanism, which converts vibration energy to electric energy. Its main parts are oscillating mass, magnets and coil for electromagnetics induction. The thesis is consisted of simulations of magnetics circuits, creating 3D model of harvester and simulations of oscillations with parameters from 3D model, magnetics simulations and with input sample of exciting vibrations.

Design of Vibration Energy Harvester with Using of Non-linear Characteristics
Rubeš, Ondřej ; Ondrůšek, Čestmír (referee) ; Hadaš, Zdeněk (advisor)
This thesis is focused on design of piezoelectric energy harvester with additional nonlinear stiffness. Linear generator has very narrow resonance frequency bandwidth. It makes the resonance mechanism very sensitive to tuning up of the resonance frequency and it can be tuned only for one narrow vibration peak. The main idea for using of the vibration energy harvester with nonlinear stiffness is to make resonance frequency bandwidth wider, so the generator will be useable for more excitation frequencies. In this thesis is used generator Midé V21BL and additional nonlinear stiffness is realized with permanent magnets.
