Abstract
This study deals with the design of an efficient small-sized bio-implantable planar spiral square stacked coils (double layer) based on inductive coupling links technique. The parasitic capacitances of the proposed design is insignificant, hence, the tuning capacitor of the equivalent circuit can be negligible. The external coil placed outside the human body with outer dimensions dout = 30 mm and inner dimension din = 7.6 mm with 15 number of turns. The internal double layer is designed to be inserted within human tissue and having outer dimensions dout = 10 mm and inner dimension din = 7.6 mm with 3 number of turns for each layer. The High Frequency Structural Simulator (HFSS 14.1) is used to design and simulate the coils in the air and within the phantom human tissue. Mathematical formulas, simulation and experimental results are introduced to validate the proposed design. The results show that the stacked coils with double layer have better efficiency than single layer by 2.7% on air and 9.71% within the phantom tissue. The results also, validated by compression with other previous researcher. To prove that the proposed double layer coil cannot damage the human tissue the SEMCAD 16.4 Software is used. The proposed design is suitable for implantable medical devices such as a nerves stimulators.
