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.
近年来，多用途主动胶囊内窥镜受到了广泛关注，但这些设备仍然存在能量限制的问题。无线供电系统被认为是克服这些设备中电源短缺问题的一种实用方法。本文主要研究了在尺寸和安全限制下，对无线能量供应系统的效率进行优化。针对传输效率、最优频率和电流以及整体系统效能，提出了一个考虑这些约束条件的数学规划模型。为了验证所提出方法的可行性，我们使用无线主动胶囊内窥镜作为实例进行了验证。所获得的效率可以作为评估系统的指标，并且可以使用所提出的方法来指导发射和接收线圈的设计。
