Biomedical implanted electronic devices such as retinal prosthesis and artificial cochlea commonly use coupling inductive coils for power and data transmission. With many parameters to be considered, exhaustive sweeping of these parameters is impractical in physical verification. This paper presents an applicable optimization procedure for coils design in a dual band transmission system proposed by our group. This procedure focuses on the optimization of two pairs of coils based on an overlapping structure which minimizes power-to-signal interference in the data transmission. We applied the optimization procedure to a practical design case, and the result showed that our semi-automatic optimization procedure can achieve both optimal power transmission efficiency and high signal to interference ratio.
