AB  - The wireless Brain Computer Interface (BCI) equipped with the Radio Frequency Power Delivery (RFPD) system normally has correct midrange power requirement as well as operating distance ranges for getting powered wirelessly over a long period continuously in order to extend its effectiveness. The BCI is a devic eneeding most importantly, the freedom of movement resulting from this uninterrupted unwired power that does not need any battery replacement or recharging times that can cause distractions of the subject persons, thereby mostly depriving the very purpose of using the BCI. This integrated RFPD system is based on transmission of high power Radio Frequency (RF) waves which is the emerging far field Wireless Power Transfer (WPT) method. This WPT method is having many advantages over other induction and microwave methods because of its safety, non-interference and high efficiency at the medium ranges. The design of all of this BCI system components especially, the low power amplifier and others like RF transceiver, maximum power Tracker and the data transfer protocol are analyzed for optimization of efficient performance for this Electro encephalogram (EEG) based application. The difficulties of integrating and outfitting this BCI with the RFPD system for the effective wireless powered operation is also immensely addressed.
