This work presents a fully battery-less and wireless (untethered) EEG readout cap. The powering system is equipped with a highly efficient and compact power transmitter mosaicked by an array of 8×11 Tx resonators in a certain pattern operating at the lowest ISM band of 6.78 MHz. The front-end's power receiver block Rx includes multi-resonators mounted all-around an EEG cap that can be worn by a subject. Furthermore, considering the subject's head which could assume different positions, a well-designed positioning system and an intelligent feeding setup are developed to balance the efficiency drop due to misalignment and to involve the most associated resonators with the powering scenario with the potential of switching off the extraneous resonators that are not engaged with Transmit and Receive (Tx-Rx) power.
