本文分析了空心线圈经皮能量传输Transformer周围人体生物组织的内部电场E和比吸收率（SAR）。使用电磁模拟器，我们创建了一个人体生物组织模型，包括干皮肤，湿皮肤，脂肪，肌肉和皮质骨。初级线圈放置在皮肤表面，次级线圈位于体内皮下。使用0.3-1.5 MHz的电频率分析了代表34岁男性受试者的模型的E和SAR值。发射功率为15 W，负载电阻为38.4 Ω。结果表明，E值低于国际非电离辐射防护委员会（ICNIRP）规定的频率为0.9至1.5 MHz之间公众暴露的限值，SAR值远低于ICNIRP规定的频率为0.3至1.2 MHz之间公众暴露的限值。
In this study, we analyzed the internal electric fieldEand specific absorption rate (SAR) of human biological tissues surrounding an air-core coil transcutaneous energy transmission transformer. Using an electromagnetic simulator, we created a model of human biological tissues consisting of a dry skin, wet skin, fat, muscle, and cortical bone. A primary coil was placed on the surface of the skin, and a secondary coil was located subcutaneously inside the body. TheEand SAR values for the model representing a 34-year-old male subject were analyzed using electrical frequencies of 0.3–1.5 MHz. The transmitting power was 15 W, and the load resistance was 38.4 Ω. The results showed that theEvalues were below the International Commission on Non-ionizing Radiation Protection (ICNIRP) limit for the general public exposure between the frequencies of 0.9 and 1.5 MHz, and SAR values were well below the limit prescribed by the ICNIRP for the general public exposure between the frequencies of 0.3 and 1.2 MHz.
