When patients are fitted with a totally implantable artificial heart (TAH), they need to be implanted with two additional devices: one for the transmission of energy and one for information. However, this is a cumbersome process that affects the quality of life of the recipient. Therefore, we investigated the use of electromagnetic coupling for the transmission of energy and information and the possibility of unifying two transcutaneous transformers for the simultaneous transmission of energy and information. While unifying the transformers, it is important to suppress the electromagnetic coupling between energy and information transmission. Therefore, we ensured that the electromagnetic fields generated from the transformer windings for the transmissions of information and energy intersected perpendicularly. If the fields are perpendicular, the electromagnetic coupling between the energy and information transmissions will be suppressed significantly. The characteristics of the simultaneous transmission of information and energy using the unified transcutaneous transformer, developed experimentally, were evaluated by changing the number of windings used for the transmission of information. The electromagnetic coupling between the energy and information transmissions was suppressed by determining the direction of the magnetic field. Moreover, the optimum number of transformer windings required for the simultaneous transmission of energy and information was determined. We concluded that the externally coupled transcutaneous transformer unified for the simultaneous transmission of energy and information performed with good transmission characteristics.
当患者植入完全植入式人工心脏（TAH）时，他们需要额外植入两个装置：一个用于能量传输，一个用于信息传输。然而，这是一个繁琐的过程，会影响接受者的生活质量。因此，我们研究了利用电磁耦合进行能量和信息传输以及将两个经皮变压器统一用于同时传输能量和信息的可能性。在统一变压器时，抑制能量和信息传输之间的电磁耦合非常重要。因此，我们确保了用于信息和能量传输的变压器绕组产生的电磁场垂直相交。如果场是垂直的，能量和信息传输之间的电磁耦合将被显著抑制。通过改变用于信息传输的绕组数量，对实验开发的统一经皮变压器同时传输信息和能量的特性进行了评估。通过确定磁场方向，抑制了能量和信息传输之间的电磁耦合。此外，还确定了同时传输能量和信息所需的变压器绕组的最佳数量。我们得出结论，为同时传输能量和信息而统一的外部耦合经皮变压器具有良好的传输特性。
