1. A method comprising the steps of:

  • providing on a substrate an array of sensing devices for detecting the contour of an object, each of the sensing devices operable to discriminate ridges from valleys of the object when an adjacent ridge and valley is spaced less than 800 microns apart, wherein each of the sensing devices includes a top surface;

    applying under at least one of normal room temperature and normal room pressure conditions a contiguous sheet film protective covering adapted for placement over the top surfaces of the sensing devices to form a sensing apparatus, the sheet film protective covering including a plurality of layers, at least one of the layers enhancing mechanical damage resistance, one of the layers of the sheet film protective covering being Mylar and at least a top layer of the sheet film protective covering being conductive and grounded.
