Originální abstrakt

This paper deals with an electromagnetic vibration energy harvester which generates electrical energy from ambient vibrations. This harvester provides an autonomous source of energy for wireless applications, with an expected power consumption of several mW, placed in an environment excited by ambient vibrations. A tuned up design of the harvester with an electromagnetic converter provides sufficient generating of electrical energy for wireless applications. The output power depends on a frequency and level of the vibration and sensitivity of the energy harvester. Our harvester includes a unique spring-less resonance mechanism where stiffness is provided by repelled magnetic forces. The sensitivity is affected only by friction forces inside the mechanism of the harvester. Ways of decreasing friction, it means an increasing sensitivity, are investigated in this paper. The increasing sensitivity of the harvester provides more generated energy or decrease of the harvester size and weight.
