    摘要: Transfer tape articles are suitable for preparing dry electrodes. The transfer tape articles include a release liner and a conductive transfer tape layer adjacent to the release liner. The conductive transfer tape layer includes a layer of adhesive and a discontinuous layer of electrically conductive shaped particles, where the shaped particles have at least one point. The adhesive envelopes the conductive particles, and at least one point of the electrically conductive particles protrudes from the conductive transfer tape layer. The conductive transfer tape layer can be a single layer of adhesive or a multi-layer construction including a first adhesive layer, a support layer, and a second adhesive layer.

    摘要: In an example, an electrocardiogram (ECG) device includes a housing, an ECG sensor, and first and second electrodes. The ECG sensor is disposed in the housing. The first electrode is accessible from outside the housing and is electrically coupled to the ECG sensor. The second electrode is accessible from outside the housing and is electrically coupled to the ECG sensor. The housing and the first and second electrodes define an ECG device electromechanical interface that is complementary to a common patch electromechanical interface that is included in at least two different types of attachment patches.
