1. A sensor comprising:
- a nonrigid cover layer;
an emitter disposed on a first side of said cover layer;
a detector disposed on said first side of said cover layer; and
a plurality of stacked independent nonmetallic adhesive layers disposed on said first side of said cover layer, wherein no portion of said adhesive layers is present in the direct optical path between said emitter and said detector.

Abstract
An optical sensor having a cover layer, an emitter disposed on a first side of the cover, a detector disposed on the first side of said cover, and a plurality of stacked independent adhesive layers disposed on the same first side of the cover, wherein the top most exposed adhesive layer is attached to a patient'"'"'s skin. Thus, when the sensor is removed to perform a site check of the tissue location, one of the adhesive layers may also be removed and discarded, exposing a fresh adhesive surface below for re-attachment to a patient'"'"'s skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.
