Neural implants have emerged over the last decade as highly effective solutions for the treatment of dysfunctions and disorders of the nervous system. These implants establish a direct, often bidirectional, interface to the nervous system, both sensing neural signals and providing therapeutic treatments. As a result of the technological progress and successful clinical demonstrations, completely implantable...
Inductive coupling is considered as one of the main stream techniques in wireless power transmission for implantable devices. In this paper, we present a generic analysis of the different topologies for wireless power transfer and arrive at boundary frequencies that separate various topologies, thereby allowing users to identify the topology that best suits the application requirements. In the meantime,...
This paper presents a study on the efficiency of wireless power transfer (WPT) via inductive coupling, used in implantable biomedical devices. The expressions for efficiency of four different topologies used for WPT have been derived and a topology has been identified that is best suited for use with biomedical implants. The efficiency derived for the chosen topology is maximized and is compared with...
