Background
Wireless power transmission for capsule robots has always posed challenges due to the unpredictable postures.
Methods
A radial transmitting coil with a novel ferrite structure is proposed, which consists of two parts with the function of converging magnetic induction lines and reducing magnetic leakage. To improve the flux density, uniformity, and shielding effectiveness, the design...
Background
The wireless power transfer system (WPTS) is a promising way to continuously provide efficient and stable power for gastrointestinal capsule robots with active movement ability.
Methods
The proposed WPTS using an optimised planar square spiral transmitting coil pair with space‐saving structure can flexibly adjust the distance between the coils according to the patient's condition, and...
This paper proposes a new prototype of wireless micro-robot system for endoscope. The micro-robot we have fabricated and tested is able to propel itself in the intestine canal of pig in an autonomous manner by earthworm locomotion. It is different from the conventional micro-robot endoscope that wireless module is used for communicating and power transfer being up to 480 mW of DC power for receiving...
