The present disclosure relates to a wearable device having a structure that prevents impedance measurement errors. The wearable device, which is used by being attached to the skin of a user, includes a plurality of electrodes spaced apart from each other, conductive members, blocking members, and absorbent members. A conductive member is positioned on one surface of each of the plurality of electrodes and comprises an exposure portion. A blocking member includes a different material from the conductive member and covers an outside of the conductive member so that the exposure portion is present within the blocking member. An absorbent member is positioned in the outside of the blocking member and comes into contact with the skin of the user.

The invention relates to a method for producing a medical electrode, comprising the following steps: (i) providing a substrate; (ii) applying a composition onto the substrate, wherein the composition comprises (a) a non-aqueous solvent and (b) an organic iridium complex compound dissolved in the solvent; (iii) heating the composition, and thereby forming a noble metal layer on the substrate.

One aspect relates to a stretchable electrode assembly for a stimulation, modulation or sensing implant comprising an electrical conductor segment comprising at least one electrical conductor which is an electrically insulated wire or cable, and at least one electrode which is adjacent to the electrical conductor segment, wherein the electrical conductor segment is at least partially embedded in a biocompatible substrate and the electrical insulation of the at least one electrical conductor comprises one or more opening(s) suitable for mechanically and electrically connecting the at least one electrode to the at least one electrical conductor of the electrical conductor segment. One aspect also relates to a stimulation, modulation or sensing implant comprising the stretchable electrode assembly as well as a method for preparing such a stretchable electrode assembly.

A method includes obtaining a measurement of an electrogram voltage between a first electrode and a second electrode disposed within a body of a subject. The method further includes, while obtaining the measurement, causing (i) a first current, which has a first frequency, to flow between the first electrode and one or more reference electrodes, and (ii) a second current, which has a second frequency, to flow between the second electrode and the reference electrodes, such that a beat voltage, which has a third frequency that is a difference between the first frequency and the second frequency and is within a frequency band of the electrogram voltage, is seen at the first electrode and the second electrode. The first electrode and second electrode are coated with an output-impedance-reducing coating that facilitates obtaining the measurement despite the beat voltage.

A conformal patch device can be provided to a patient. The patch device can include sensors configured to be positioned over a chest of a patient. The sensors can include PPG sensors, ECG sensors, and SCG sensors. The conformal patch device can adhere to a single continuous area of the chest. Some sensors may attached to a viscoelastic substrate to achieve mechanical isolation from other patch components. The conformal patch device can capture measurements from the sensor doing a time window sufficient enough to detect disordered breathing. The system can determine disordered breathing and related cardiorespiratory parameters during the time window for the patient using the sensor measurements.
