A micro electromagnetic generator for vibration energy harvesting
Indexed incrossref
Abstract
Vibration energy harvesting is receiving a considerable amount of interest as a means for powering wireless sensor nodes. This paper presents a small (component volume 0.1 cm<sup>3</sup>, practical volume 0.15 cm<sup>3</sup>) electromagnetic generator utilizing discrete components and optimized for a low ambient vibration level based upon real application data. The generator uses four magnets arranged on an etched cantilever with a wound coil located within the moving magnetic field. Magnet size and coil properties were optimized, with the final device producing 46 µW in a resistive load of 4 kΩ from just 0.59 m s<sup>-2</sup> acceleration levels at its resonant frequency of…
