The goal of this study is to introduce practical state-of-the-art considerations for designing a highly efficient power generation, transmission, and conversion chain system, PGTCC, to power up the front-end's electronics that acquire satisfactory EEG signal acquisition in a portable wireless and battery-free EEG cap. Several solutions, strategies, and unique configurations have been presented to reach this goal, including, a highly efficient and compact resonance-inductive link, multi-resonator power transfer, use of magnetized materials to improve power transmission efficiency, closed-loop power transmission, and a highly efficient power conversion chain. The proposed design has the potential to significantly improve the total efficiency and supply stable power for the front-end units that include the EEG signal, filtering, noise cancelation amplification units, processing units, and transceivers.
