METHOD AND APPARATUS CORRESPONDING TO AN ASPERITY DETECTION SENSOR SURFACE

摘要

A plurality of contact sensor pixel elements (202) are provided (101) along with a plurality of electrically conductive balls (302, 403). By one approach these balls are each sized at least substantially similar to the contact sensor pixel elements. If desired, by one approach, these balls are provided in a pre-arranged pattern separate from the plurality of contact sensor pixel elements. By one approach this pre-arranged pattern provides for alignment and registration of the balls with the contact sensor pixel elements when the two are brought into contact with one another. Each of the plurality of electrically conductive balls is then affixed in contact with one of the plurality of contact sensor pixel elements such that substantially none of the plurality of contact sensor pixel elements contacts more than one of the electrically conductive balls.
