1. A device comprising:
- a pad region having a cavity,wherein the cavity comprises a cavity opening, and the cavity extends from the cavity opening to an inside surface that is opposite of the cavity opening,the cavity is positioned between a first end of the pad region and a second end of the pad region, opposite the first end, anda bottom surface area of the pad region is greater than a bottom surface area of the cavity opening;
a first light-shielding layer, coupled to the pad region, wherein the first light-shielding layer has an opening that overlaps with at least a portion of the cavity opening; and
an adhesive layer, coupled to the first light-shielding layer, wherein the adhesive layer extends past at least one edge of the first light-shielding layer.

Abstract
A flexible sensor pad includes a cavity to hold a sensor unit with an attached cable. According to one aspect of the present invention, a light-shielding layer is coupled to a bottom surface of the sensor pad, surrounds the sensor unit, and extends past two sides of the sensor pad. A transparent adhesive layer is coupled to the light-shielding layer and extends past two sides of the light-shielding layer. Another light shielding layer is coupled to a top surface of the sensor pad and covers the sensor unit. The cable divides the sensor pad into a first side and a second side which are mirror images of each other.
