1. An apparatus that senses an edge pressure profile generated by an edge of a pressure source, comprising:

  • at least one sensor strip having at least a resistive strip;

    at least one electrical source connected to the sensor strip;

    a conductive sensor membrane extending adjacent to and spaced from the sensor strip; and

    at least one electrical sensor connected to the resistive strip;

    wherein, when an edge pressure is applied to the sensor membrane, the sensor membrane is deformed to electrically contact the sensor strip.
