A wearable electrode includes an electrode (203) fixed to garment (21) such that the electrode (203) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper left part of the body of a wearer (20), and an electrode (204) fixed to the garment such that the electrode (204) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper right part of the body of the wearer (20). The electrodes (203, 204) are installed such that the attaching positions gradually descend from the ventral side to the dorsal side with the wearer (20) standing upright, or the attaching positions gradually ascend from the ventral side to the dorsal side with the wearer (20) standing upright.

A connector assembly for coupling with one or more electrodes includes one or more cables with wires. A plug is electrically coupled with an end or ends of the cables. An electrode connector structure is electrically coupled with the cables and includes a body that is configured for forming an internal space. A cantilevered first arm has an end that cantilevers toward the internal space. The cantilevered first arm has a rest position and a flexed position. A stationary second arm and arm end extend into the internal space opposite the first arm. At least one of the ends of the cantilevered first arm and stationary second arm include an electrical contact. In the rest position, the end of the cantilevered first arm is positioned opposite the stationary second arm a first distance. In the flexed position, the cantilevered arm, moves away from the stationary second arm to separate the ends to a greater distance to receive the electrode and returns to the rest position to grip the electrode.

A mono-layer electrode sensor suitable for a multitude of electrophysiology testing applications is disclosed. The electrode sensor can include a mono-layer of conductive film shaped with a soft-form geometry that is modifiable to a targeted size tailored to a patient. The conductive film includes a sensing area that is complementary to a size and morphology of a body structure of the patient. The conductive film can have a connector coupled to the sensor, and the skin adherent side can have a bio-compatible hydrogel coated there over including a non-conductive material formed over the connector portion of the conductive film.
