Abstract

The use of energy harvesting systems is becoming a more prominent research topic in supplying energy to wireless sensor nodes. The paper will present an analytical 'toolbox' for designing and modeling a vibration energy harvester where the moving mass is suspended magnetically. Calculations from the presented model and measurements from a prototype are compared, and the presence of system non-linearities is shown and discussed. The use of the magnetic suspension and its equivalent hardening spring suspension leads to the system's non-linearity, demonstrating a broad band response and 'jump' phenomenon characteristic. The benefits of these are discussed and the system's performance is compared with those from literature, showing similarity.
