Mechatronic Proposal of Electromagnetic Vibration Power Generator
Jurosz, Pavel ; Houška, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with modifications to the construction of vibration-to-electricity energy converter, which is one of possible solutions to problem of sustainable and stable energy source for wireless sensor supply. Upon the exploration of the present state of this problem, new construction of generator is proposed. The aim of this proposal is to enhance the existing generator properties with respect to retention of its dimensions and its weight. Results obtained by simulations of model with proposed parameters are presented and analysed.

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.
