Therapeutic electrical stimulation (TES) is electrical stimulation to treat disorders caused by abnormalities in nerves. We have been researching implanted TES that stimulates objective nerves directly inside the body. Prior to this, separate coils were used in implanted TES to transmit power and signals. However, the two-coil system presents several problems. For example, it is necessary to carefully design both coils because the one for power transmission is more powerful than the one for signal transmission, and the power magnetic field interferes with the signal magnetic field. That makes it extremely difficult to design these coils flexibly. To solve this problem, we have begun research on establishing a different method that would increase the flexibility with which coils could be designed. The concept underlying this new approach was to transmit power and signals simultaneously with the same magnetic field. To achieve this, we superimposed the signal on the power. In the first step in this research, we ascertained that this superimposed system of transmission could drive the system for implanted TES.
