Transcutaneous power-transmission coils continuously transmit electric power into implanted devices, such as FES (Functional Electrical Stimulation), implanted artificial Hearts and so on. For a transcutaneous powertransmission system, a transcutaneous signal-transmission coil is required to monitor and control the implanted devises. However, in the event that transcutaneous power-transmission coils are dislocated, power-transmission decreases. It is therefore necessary to determine how they are dislocated for monitoring the state of power transmission. In this paper, we study a system to determine the dislocation of coils by measuring the current value of the signal coil outside the body, The dislocations and the shift direction of the coils can be evaluated within about ± I5[mm]. We can determine each dislocations of an X and Y direction independently by using a figure of if coil.
