Description

technical field [0001] The invention relates to a magnetic resonance wireless energy supply method and device for a capsule diagnosis and treatment system, belonging to the field of medical electronics. Background technique [0002] With the rapid development of electronic technology, the functions of capsule endoscopes are continuously enhanced, and the power consumption is also increasing. The traditional battery power supply method can no longer meet the high power consumption demand of the microsystem, and the energy supply problem has become one of the main technical "bottlenecks" restricting the actual large-scale application of the capsule diagnosis and treatment system. Using wireless energy supply technology is an effective way to solve this problem. [0003] At present, the wireless energy supply technology based on the capsule endoscope system is realized by using the principle of electromagnetic induction coupling inside and outside the body. This energy supply...
