Design of planar electromagnetic generator for sea drifter
 Almáši, Matej ; Rubeš, Ondřej (referee) ; Hadaš, Zdeněk (advisor)
Unfixed buoys are an important part of sea and sea current monitoring. It is important that these buoys display a great amount of self-sufficiency. Electronic components of the buoy are conventionally powered by batteries, however there is an attempt to replace them with more self-sufficient sources that utilize energy from sea waves. For this purpose, so called “energy harvesters” that utilize electro-mechanic conversion are being developed. This thesis is focused on raising the power output of an energy harvester that is currently being developed at the FME BUT by finding the ideal parameters of the generating coil. An electro-mechanic model was developed which was then utilized to perform a sensitivity analysis. The result of the analysis was a set of coil parameters that resulted in the greatest power output. Subsequently, a coil prototype was manufactured, and the power output was measured experimentally. The root mean square value of the generated power was PRMS = 152.7 µW, which less than expected by the used model, however the coil winding didn’t fill up the space dedicated to it to the expected degree.
