摘要

本文介绍了一种非线圈源，用于提高各种医疗应用中可植入设备的无线电力传输效率，这些设备包括心血管设备、小肠内窥镜和大脑神经刺激器。对于每种应用，解析求解了功率传输效率的边界和达到该边界的最优源。结果表明，根据可植入器件的深度，功率可以传输到亚毫米级接收器，效率范围为- 57 dB至- 33 dB，比现有基于线圈的源系统性能高出6.6倍。本文所介绍的技术可广泛应用于其他医学领域。

NON-COIL, OPTIMAL SOURCES FOR WIRELESS POWERING OF SUB-MILLIMETER IMPLANTABLE DEVICES

This paper presents non-coil sources to improve the wireless power transfer efficiency for implantable device used in various medical applications — cardiovascular devices, endoscope in the small intestine, and neurostimulator in the brain. For each application, a bound on the power transfer efficiency and the optimal source achieving such bound are analytically solved. The results reveal that depending on the depth of the implantable devices, power can be transferred to a sub-millimeter scaled receiver with the efficiency ranging from −57 dB to −33 dB, which is up to 6.6 times higher than the performance of existing coil-based source systems. The technique introduced in this paper can be broadly applied to other medical applications.
