Bioelectric sensor device and methods

A bioelectric sensor device for sensing bioelectric data from a human body, the device comprising:

• a flexible dielectric substrate comprising a first major surface, a second major surface, a sensor array portion comprising a center, and a contact array arm extending from the sensor array portion to a distal end thereof, wherein the sensor array portion of the substrate comprises a left edge, a right edge, a top edge between the left edge and the right edge, and a bottom edge between the left edge and the right edge;
• a plurality of sensors arranged in a sensor array on the sensor array portion of the substrate, wherein each sensor of the plurality of sensors is configured to sense bioelectric data when in contact with skin;
• an electrically conductive network located on the substrate, wherein the electrically conductive network comprises a plurality of electrically conductive paths, wherein each electrically conductive path of the plurality of electrically conductive paths extends from one sensor of the plurality of sensors to a contact array on the contact array arm, wherein each electrically conductive path corresponding to at least two adjacent sensors comprises a first conductive path extending between the respective sensor and the center of the sensor array portion;
• and
• a plurality of lines of weakness formed in the sensor array portion of the substrate, wherein each line of weakness of the plurality of lines of weakness is configured to enhance separation of the sensor array portion of the substrate along a separation line to remove a sensor of the plurality of sensors from the bioelectric sensor device, and further wherein at least one line of weakness of the plurality of lines of weakness intersects an electrically conductive path of the plurality of electrically conductive paths;
