Abstract
A pulse oximeter sensor comprising a light emitter and a detector disposed on a substrate layer with a plurality of perforations or variations in thickness between the light emitter and the detector. The plurality of perforations or variations in thickness blocks or scatters light shunted via the substrate layer from the light emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light.
