Power transmission by induction has many advantages in the biomedical field. By avoiding the need to cross the epidermal barrier, the risk of infection is greatly reduced. For reasons of comfort and implantability, a flexible system is almost an obligation for devices of a certain size. Although in the context of the project carried out at the CEAM at LAI, the choice has for the moment been made to use sets of Litz wire coils, the aim of this semester project was to study the feasibility of an equivalent system on PCB (Printed Circuit Board). After a series of simulations of different coil designs were carried out, an order for a first coil design was made and various tests on the coils were carried out to validate the model used. Although the first results brought by this set of coils are in line with the expected results, some approximations in the model and the accuracy of the simulation would have justified the order of at least one new set of coils. Unfortunately, the extended order lead times have caused the project to be delayed and although the results are not fundamentally bad, they are below the expected results. At the same time, an initial research was carried out into the possibility of using a Cockcroft-Walton generator to increase the voltage at the output of the coil set.
