For the long-time monitoring of electrocardiograms, electrodes must be skin-friendly and non-irritating, but in addition they must deliver leads without artifacts even if the skin is dry and the body is moving. Today's adhesive conducting gel electrodes are not suitable for such applications. We have developed an embroidered textile electrode from polyethylene terephthalate yarn which is plasma-coated with silver for electrical conductivity and with an ultra-thin titanium layer on top for passivation. Two of these electrodes are embedded into a breast belt. They are moisturized with a very low amount of water vapor from an integrated reservoir. The combination of silver, titanium and water vapor results in an excellent electrode chemistry. With this belt the long-time monitoring of electrocardiography (ECG) is possible at rest as well as when the patient is moving.
对于心电图的长期监测，电极必须对皮肤友好且无刺激性，但除此之外，即使皮肤干燥且身体移动，它们也必须提供无伪迹的导联。如今的粘性导电凝胶电极并不适用于此类应用。我们已开发出一种由聚对苯二甲酸乙二酯纱线制成的绣花纺织电极，该电极通过等离子体镀银以实现导电性，并在顶部镀有超薄钛层以进行钝化处理。其中两个电极嵌入到胸带中。它们通过集成储液器中极少量的水蒸气进行保湿。银、钛和水蒸气的组合产生了优异的电极化学性能。借助这条胸带，无论是在患者休息时还是活动时，都能够进行心电图（ECG）的长期监测。
