The subjects addressed in this document fall under the topic of wireless power transmission (WPT). Power is transferred using a novel coupling technique based on electrical coupling and resonance across a distance of 5 meters with 40% efficiency. The experimental results obtained so far suggest that the efficiency of the proposed system remains stable when the relative orientation between the transmitter and the receiver is altered. The prototypes used in the experiments measure 16 by 16 cm by 3.7 cm at most. The ratio between the range of the system and the maximum dimension of each prototype is therefore around 30.
