Sensor product for electric field sensing

A sensor product web for electric field sensing, the sensor comprising:

• a substrate comprising a continuous roll of material;
• a plurality of sequential electrically conductive areas on a surface of the substrate;
• a plurality of conductors on the surface of the substrate, the conductors being parallel to each other and extending in a longitudinal direction of the sensor product web, wherein only one electrically conductive area is in contact with one conductor in a longitudinal length of the sensor product web, wherein a maximum number of the electrically conductive areas is equivalent to a maximum number conductors;
• a plurality of bridges each comprising dielectric and electrically conductive material extending between the conductive areas and one of the conductors, the bridge enabling cutting the substrate at a plurality of points to form output including at least one electrically conductive area and at least one associated conductor;
• and
• a plurality of outputs operatively connected to one of the conductors.
