Angular misalignment is a key issue in wireless p ower transf er systems f or visual p rosthesis, such like retinal p rostheses. The weakened f lux linkage due to the receiver misalignments in the eyeball would significantly imp air the p ower cap acity and efficiency. To increase the magnetic coup ling strength and imp rove the misalignment tolerance, A novel three-dimensional transmitting structure with three transmitting coils at an angle of 120° to each other is p resented in this p ap er. It shows that the new structure can eff ectively comp ensate the f lux linkage loss caused by the angular misalignment of the receiver, and theref ore maintain a high p ower cap acity and efficiency.
