摘要

由于接收功率和可控性的限制，无线电力传输对于植入式设备和主动式多功能胶囊内窥镜来说仍然是一个开放的挑战。本文介绍了一种具有选择性工作频率控制的新型高性能谐振无线电力传输系统。该系统由一个可控发射单元和多个接收单元组成。发射单元能够在多个期望的频率上产生强大的替代磁场，而每个接收单元被设计成在期望的频率上与发射信号共振。这使我们感兴趣的区域在70至100 kHz的频率范围内实现了选择性无线电力传输，在100 kHz频率和距离传输线圈9厘米的距离下，最大电力传输效率为35%。此外，该系统成功地通过加热线圈对每个软执行器的形态变化进行独立的温度控制，使软胶囊内窥镜能够运动。

Frequency-selective and high-performance wireless power transmission system for a multifunctional capsule endoscope: A feasibility study

Due to limitations in receiving power and controllability, wireless power transmission remains an open challenge for implantable devices and the active multifunctional capsule endoscope. This work introduces a novel high-performance resonant wireless power transmission system featuring selective operating frequency control. The system is comprised of a controllable transmitting unit and multiple receiving units. The transmitting unit is capable of generating powerful alternative magnetic field at multiple desired frequencies, while each of the receiving units is designed to resonate with the transmission signal at a desired frequency. This enabled selective wireless power delivery in our region of interest across a frequency range from 70 to 100 kHz, with maximum power transfer efficiency of 35 % measured at frequency of 100 kHz and distance 9 cm from transmission coil. Furthermore, this system demonstrated successful independent control of the temperature by heating coils for the morphology changes of each soft actuator, enabling the locomotion of the soft capsule endoscope.
