N2 - This paper presents a novel 2-layer FR4 PCB extended coil design of the wireless power transfer (WPT) system for deep brain stimulation-implanted integrated circuits. The dual-side property of the FR4 is utilized and the coil diameter is optimized. This design can extend the transmission distance and improve the transfer efficiency. Implanted coil occupies an area measuring 5 × 5 mm2 and is fabricated on an FR4 substrate. At distance of 10 mm, the proposed 4-coil WPT using 2-layer extended coil improves the maximum transmission efficiency by 25%, compared to the equivalent traditional design. Finally, figure-of-merit (FOM) is defined and the proposed system has the optimal efficiency among PCB-based designs.
