LSI main research lines

Wireless Power Transfer

WPT basically deals with the transfer of energy between two coils magnetically coupled and usually separated by air. In the nineteenth century Nikola Tesla tried to transfer large amounts of energy through coils over long distances. However, this idea was abandoned because the low efficiency of the transfer system and various problems related to limited technology of that time. However, with the technological evolution, many new applications have emerged, which do not require very large amounts of energy or do not require long distances. These facts along with the discovery of methods to optimize transferred power makes this an area of great interest in the scientific community, being present in a large number of periodicals related to power electronics.

Digital Signal Processing

Summary Digital signal processing techniques are applied in many lines of research in LSI. However, we have recently started a line of research with the application of heuristic methods and neural networks. An article published in the year 2016 shows the application of some techniques in vital signs of the human body.

Energy Harvesting

We have a work done by the group on energy harvesting using piezoelectric patches. In the studies already conducted by the group, these energy collectors were analyzed in a cantilever beam subjected to external mechanical stimuli. The system model was evaluated and the results published in a conference. The objectives of this line of research are to design and evaluate a system of energy harvesting with different sources. Also, to develop a self-tuning system in order to guarantee maximum efficiency.
