Variable Frequency on Wireless Power Transfer for Pacemaker using Embedded Technology

As the development of implantable devices have become increasingly popular in modern medicine. These devices have a wide range of applications, such as health monitoring, disease prevention, delivery of a therapeutic regimen, biomimetic prosthesis, electrical stimulation of nerve tissue and recording of neural electrical activity are the basis of emerging prostheses and treatments for spinal cord injury, stroke, sensory deficits, and neurological disorders. The development of implantable biomedical devices, the rechargeable battery is applied to improve the life of implantable devices. Inductive transcutaneous power transfer, as a suitable way of charging the implantable rechargeable batteries, is widely used. In this paper, a model of inductive transcutaneous power transfer is set up to descript the relationship with coupling coefficient, load resistance and conversion efficiency.
