Abstract
The paper presents two example approaches to energy harvesting. Mechanical energy harvesting system is based on vibrational minigenerator. Basic relations of its analytical model are given in order to obtain an idea about the operating conditions. Electromagnetic harvesting system is based on tuned resonant nano-structure. Its concept allows impedance matching in order to operate in given frequency range. The matching properties are verified by means of numerical finite element analysis. For power management of vibration energy harvesting system several circuit design concepts are presented together with simulation results and basic properties comparison.
