近年来，多用途有源胶囊内窥镜已经引起了相当大的关注，但是这些设备仍然受到能量限制。无线供电系统被认为是克服此类设备中的电力短缺问题的实用方法。研究了具有尺寸和安全约束的无线能量供应系统的效率优化问题。提出了一个数学规划模型，其中考虑了这些约束条件的传输效率，最佳频率和电流，以及整体系统的有效性。为了验证所提出的方法的可行性，我们使用一个无线主动胶囊内窥镜作为说明性的例子。所获得的效率可以作为评价系统的一个指标，所提出的方法可以用来指导发射和接收线圈的设计。
Multipurpose active capsule endoscopes have drawn considerable attention in recent years, but these devices continue to suffer from energy limitations. A wireless power supply system is regarded as a practical way to overcome the power shortage problem in such devices. This paper focuses on the efficiency optimization of a wireless energy supply system with size and safety constraints. A mathematical programming model in which these constraints are considered is proposed for transmission efficiency, optimal frequency and current, and overall system effectiveness. To verify the feasibility of the proposed method, we use a wireless active capsule endoscope as an illustrative example. The achieved efficiency can be regarded as an index for evaluating the system, and the proposed approach can be used to direct the design of transmitting and receiving coils.
