摘要无线能量传输被认为是解决无线胶囊内窥镜（VCE）能量不足的一种可行方法。然而，大多数患者在诊断期间不能忍受长时间躺在固定的发射线圈中。为了研制一种用于VCE的便携式无线电能传输系统，提出了一种小型化的发射线圈和一种可充电电池驱动的便携式逆变电路。耦合线圈为28匝发射线圈和6股接收线圈，并考虑了稳定性和安全性。根据便携式原理设计了驱动电路。实验结果表明，该集成系统能够以30帧/s的帧率、320 × 240的分辨率为双头VCE连续供电8 h以上。便携式VCE具有临床应用的潜力，但需要进一步的改进和测试。
Abstract Wireless power transmission is considered a practical way of overcoming the power shortage of wireless capsule endoscopy (VCE). However, most patients cannot tolerate the long hours of lying in a fixed transmitting coil during diagnosis. To develop a portable wireless power transmission system for VCE, a compact transmitting coil and a portable inverter circuit driven by rechargeable batteries are proposed. The couple coils, optimized considering the stability and safety conditions, are 28 turns of transmitting coil and six strands of receiving coil. The driven circuit is designed according to the portable principle. Experiments show that the integrated system could continuously supply power to a dual-head VCE for more than 8 h at a frame rate of 30 frames per second with resolution of 320 × 240. The portable VCE exhibits potential for clinical applications, but requires further improvement and tests.
