Dispositivo de geração e monitoramento de sinais para avaliação de sistemas de transferência de energia sem fio

Abstract

The Wireless Power Transfer is a topic that got a lot of atention in 19th century, due to scientist Nikola Tesla, who conducted experiments proving its effectiveness. The concept has regained great attention in recent years with advances in technology, been applied to transportation systems, medical devices, among others. The present work is directed towards the development of a device to generate and monitor implantable medical devices, without the need for surgicall procedure to verify maintenance requirement and baterry recharging. By implementing a module for setting the frequency of the electronic signal and using the concept of magnetic coupling, there is the possibility of monitoring the current that the equipment consumes inside the patient, by means of the external secondary circuit, and, from that, obtaining the results in the external device, by means of the primary circuit, where the collection will be performed and presented in an interface for the user. With the premise presented, the proposed work was able to deliver an initial implementation of a device that integrates the basic functionality of electronic equipment, such as an oscilloscope and function generator, commonly used in testing wireless power transfer circuits, even though the signal acquisition results did not present the expected result.
