1. A non-invasive, electrooptical sensor for removable attachment to the skin of a patient, comprising:
- a flexible substrate;
a light emitter mounted on a first portion of the substrate;
a light detector mounted on said first portion of the substrate;
a plurality of conductive lines on the first portion of the substrate connected to the light emitter and the light detector;
a second portion of the substrate which is folded over to cover the first portion of the substrate, with openings in the second portion over the light emitter and the light detector; and
a flexible conductive layer on a surface of the second portion of the substrate covering a portion of said lines connected to the light detector.

Abstract
A conformable sensor which uses a flexible substrate, preferably a polyester strip is disclosed. The emitter and detector are mounted on one portion of the strip with conductive traces connecting to them. The second portion of the strip is folded over to cover the emitter and detector and traces, with openings for the emitter and detector. A conductive coating is applied to the strip to provide shielding from electromagnetic interference. Preferably, a second portion of the strip, which folds over the first portion, also has a Faraday shield covering the opening over the detector.
