A wearable diagnostic electrocardiogram (ECG) garment is disclosed herein. The wearable diagnostic ECG garment comprises a garment body, screen-printed electrodes positioned on the body, and screen-printed wires positioned in the garment body, each of the screen-printed wires connected from a central connector module to a screen-printed electrode.

A monitor comprises circuitry to receive a signal and process the signal to monitor at least one characteristic of a subject, and a flexible polymer casing forming a waterproof enclosure for the circuitry. The flexible polymer casing is infused with a conductive material at location to form infused electrode that extends from an exterior of the flexible polymer casing to an interior of the flexible polymer casing, and the infused electrode is coupled to the circuitry so as to allow the signal to pass from outside the flexible polymer casing to the circuitry. A polymer in a portion of the flexible polymer casing that is infused with the conductive material at the location is cross-linked with a polymer in a portion of the flexible polymer casing that is not infused with the conductive material.

A method of manufacturing a skin-compatible electrode (100) comprises printing a circuit pattern (P1) onto a flexible substrate (200) to form an electrically conductive pattern including an electrode pad area (301). A layer of an adhesive composition (401p) is printed in a second pattern (P2) onto the electrode pad area (301) to form an adhesive interface layer (401). The adhesive interface layer (401) is a dry film formed from the adhesive composition (401p) comprising an ionically conductive pressure sensitive adhesive composition comprising a resin (R), an ionic liquid (I), and optionally electrically conductive particles (P). A layer thickness and material of the flexible substrate, the conductive pattern, and the conductive adhesive interface have relatively low stiffness in plane of the flexible substrate (200).

An attachment tape is configured such that a light emitter and a light detector are mounted on the attachment tape and such that the attachment tape is wrapped around a tissue so as to be attached to the tissue. The light emitter is configured to emit light. The light detector is configured to detect the light emitted from the light emitter. A width dimension of the attachment tape is gradually narrowed from one point along a longitudinal direction of the attachment tape toward another point at a distal end of the attachment tape.

The present invention relates to a non-invasive cardiac monitoring device that records cardiac data to infer physiological characteristics of a human, such as cardiac arrhythmia. Some embodiments of the invention allow for long-term monitoring of physiological signals. Further embodiments allow for processing of the detected cardiac rhythm signals partially on the wearable cardiac monitor device, and partially on a remote computing system. Some embodiments include a wearable cardiac monitor device for long-term adhesion to a mammal for prolonged detection of cardiac rhythm signals.
