title: Relative location estimation of power-receiver from transmitter for in vivo robotic capsules.
abstract: This paper presents an estimation method of the relative location of the power-receiver from the transmitter for in vivo robotic capsules. The proposed method utilizes the fact that the needed current for driving the power transmitter is increased when the receiver coil is inductively coupled with the transmitter coil. By investigating the current increase characteristic according to the relative locations of the receiver, we draw an estimation strategy on the relative location of power-receiver from the transmission coil.
