The Research on A Transcutaneous Energy Transmission System for A Novel Rechargeable Cardiac Pacemaker

这项技术需要一个电源，使用经皮变压器来更换可充电心脏起搏器的电池。提出并制作了一种用于谐振式转换器的扁平变压器，它可以在一个大的可变人体皮肤间隙中传输几瓦的功率。二次变压器将被植入10 mm深的皮肤下，一次变压器将被放置在二次变压器的顶部，在身体外部。这种间隔不能假设是恒定的；在电源运行过程中，核心的对准和相互之间的距离肯定会发生变化。通过使用具有10 mm气隙的新型变压器，转换器可以通过完整的皮肤为新型心脏起搏器电池供电。对变压器内部磁通分布的假设进行了分析，并用实验装置测量了耦合系数和转换效率。在我们的实验动物体内，高达1W的功率水平已经安全地通过组织传递。此外，在长期暴露于经皮电源产生的电磁场后，活组织中没有观察到明显的负面影响。

The technique would need a power supply wihch uses a transcutaneous transformer to change the battery of rechargeable cardiac pacemaker. A flat transformer for a resonant converter which transfers several W of power across a large variable human skin gap is presented and built. The secondary of the transformer would be implanted under the skin 10 mm depth and primary of the transformer would be placed on top of the secondary, extemal to the body. This spacing cannot be assumed constant ; the alignment of the cores and distance between them would certainly vary during the operation of the power supply.The converter can power a novel cardiac pacemaker battery through intact skin by utilizing a novel transformer with an air gap which is 10 mm. An analysis for a presumption on magnetic flux distribution in the transformer is presented, and coupling coefficient and conversion efficiency are measured with an experimental set up. Power levels of up to 1 W have been safety transmitted across the tissue in our laboratory animal. Furthermore, no apparent negative effects have been observed in living tissue after long-term exposure to electromagnetic fields generated by a transcutaneous power supply.
