The present disclosure provides systems, apparatuses, and methods for use of wearable electrode assemblies. The electrode assemblies improve comfort by providing increased overall surface area of their bottom surfaces, which make contact with the patient's scalp and hair. Collapse, compression, or telescoping of the bottom surface will thereby decrease the direct force and/or pressure applied by the distal member or members of the bottom surfaces to the skin. This may be advantageous in patients who have little to no hair in electrode contact areas, patient populations that are particularly skin-sensitive, and/or patients which must wear the electrode assemblies of an extended time period. The electrode assemblies further include structures to dispense and/or maintain conductive gel placed over the patient's skin, thereby maintaining electrical connection quality, and/or to facilitate the clearing of skin and/or hair prior to establishing an electrical connection.

The invention comprises providing electric stimuli, which are generated by forming the following ringing circuit: active electrode—inductive storage unit—passive electrode—interelectrode tissues—active electrode, the electric stimuli creating oscillations which are used as a test signal. In one variant of the method, the electrodes are successively applied (in another variant—moved uniformly) across the skin area. Every time the electrodes-to-skin contact is detected, the oscillation parameters are recorded after a delay. Moreover, the values of parameters can be averaged. The invention allows for both combined and disjointed (i.e. separated) electrode placement. An optimal zone for electropulse therapy is identified by a minimal or maximal value of one or more parameters of the aforementioned oscillations and the use of the principle of small asymmetry. The invention further provides for an increase in the accuracy with which zones optimal for electropulse therapy are identified and localized.

The present disclosure relates to a device configured to be adhered to the surface of a mammal for recording physiological signals. The device may include a housing enclosing a circuit board and a flexible wing extending from the housing. The device may include an electrode coupled to the flexible wing and an electrical trace for transmitting an electrical signal between the electrode and the circuit board. The electrical trace may have an insulator with a conductive material and resistors printed on the surface of the insulator. The trace layer may include conductive vias for transmitting the signal from a bottom of the trace layer to a top of the trace layer. The housing may include a battery having a battery terminal connector configured to provide electrical access to both terminals on a single side of the battery. The housing may include a floating trigger button.

The battery terminal connector can present both the conductive traces to the outer surface for coupling to a circuit board. The device can assess the physiological signals to infer a likelihood of arrhythmia of a user.

An electrode carrier system includes one or more electrode assemblies having an electrode body. One or more tubular members extend from the electrode body and define a lumen terminating in a distal opening. The electrode assemblies carry a reservoir containing a conductive fluid or gel. The reservoir is in fluid communication with the lumens in the tubular members, and the electrode assemblies are typically supported on a backing which may optionally be configured as a headband. Systems are for tracking patient movement may be used in combination with the electrode carrier system.
