Abstract :
A novel integrated omnidirectional wireless power receiving circuit for wireless powering endoscopy is presented. Effectively combining energy from all directions, the proposed circuit achieves an efficiency level that is 16.2% higher than the previous best results. Benefiting from this circuit design, the whole power link of the wireless endoscopy attains a maximal overall efficiency of 5.4% at a position near the back of the human body.
