Wireless Power Transfer System for Endoscopic Capsule Robot

Park, Wanjoo ;   Kim, Laehyun

Robotic capsule endoscopy is a revolutionary procedure for examining the entire gastrointestinal tract by active locomotion of the capsule robots. However, the battery module inside the capsule cannot provide enough power to propel the capsule due to the limited battery size. In order to address this limitation, we suggest a novel method for wireless power transfer to the capsule robot by using a pair of Helmholtz transmitting coils and a multi-core receiving coil in high operating frequency.
