Sensor-compatible overlay

A method comprising:

• forming a plurality of conductive elements over a plurality of measurement electrodes for an array of fingerprint sensors;
• wherein the plurality of conductive elements is disposed between a first surface and a second surface, and orthogonal to the first surface at a point at which a fingerprint feature is disposed,
• wherein the conductive elements are distributed asymmetrically with the plurality of the measurement electrodes, and
• wherein a first conductivity created by the plurality of conductive elements is substantially greater than a second conductivity created by the plurality of conductive elements.

An overlay comprising:

• a first surface disposed proximate to a plurality of capacitance measurement electrodes;
• a second surface configured to provide a point of contact for a fingerprint feature;
• and
• a material disposed between the first surface and the second surface, the material comprising conductive elements disposed in the material such that the conductive elements are aligned in a first direction from the first surface to the second surface, wherein a first conductivity in the first direction is greater than a second conductivity in at least one other direction,
• wherein the conductive elements are distributed within the material asymmetrically with measurement electrodes for an array of fingerprint sensors.
