| Summary: | Micro energy harvester has been a topic of interest due to the raising popularity
of portable and wearable devices, which require continuous supply of power
for its operation. As one of the means to harvest kinetic energy from relative
motion of magnet and coil, microcoil were studied and developed intensively
to realize small yet powerful power sources for the portable devices. However,
these researches have been lacking in the analysis of fundamentals relating
to the coil parameter and performance. This project aims to fill the gap by
characterizing various coil arrangements and parameters of magnetic micro
energy harvester. COMSOL simulation was conducted to collect data for
analysing numerous parameters such as wire density, the gap between
magnet and coil, the linear velocity of magnet, and coil wire radius.
Experiments were subsequently carried out in the laboratory to verify some of
the selected simulation configurations performed earlier. The result of
simulation and experiment are in good agreement to one another, thus
corroborating the simulation findings that were used to deduce most of the
conclusions in the report. |
