| Popis: | Functional electrical stimulation (FES) is a therapy used in the rehabilitation of lost-movement functions by applying electrical stimulation to paralyzed extremities. We adapted the implanted direct-feeding method to apply stimulation, in which small implanted stimulators were placed under the skin at a depth of 20 mm, and stimulus energy and signals to control the devices were applied to them with a mounted system using magnetic coupling. This method had two main advantages in that it had no percutaneous points and it provided highly precise stimulation. The sizes of the mounted coil and the implanted coil were quite different so that the coupling between each was extremely low. To retain this disadvantage, the implant coil had a high-aspect ratio ferrite core, which gave the implant coil a magnetic direction for easy feeding and communication. Therefore, the magnetic fluxes from the mounted coil for feeding and communication had to be generated in the same direction inside the mounted coil. We propose a mounted coil that is able to generate such a magnetic flux, and tested and verified the possibility of whole area feeding and communication with it. |
