Estudo sobre transferência indutiva de potência: aplicações biomédicas

Abstract

This work presents a study on wireless power transfer technology applied to implantable medical devices. Initially, an introduction to contactless electrical energy transfer is provided, covering historical milestones in the field, as well as a brief description of wireless transfer types found in the literature. Subsequently, the text delves into the description of inductive and resonant inductive systems, highlighting their specific characteristics that contribute to Wireless Transfer Power (WTP). The features of both the transmitting and receiving coils involved in the wireless transmission process are also discussed. Furthermore, the work includes a literature review of technology applications, showcasing examples of inductive and resonant inductive links in medical devices. Additionally, safety challenges and recommendations for patients using wireless transfer systems are addressed. Finally, concluding remarks highlight areas currently prominent in research and scientific development, along with potential topics for future work.
