1. A sensor comprising:
- a light emitter;
a light detector;
a layer coupled to the light emitter and the light detector; and
a crimping member coupled to the layer between the light emitter and the light detector, the crimping member forming a crimped portion in the layer, wherein the crimping member is configured to attenuate light shunted from the light emitter to the light detector such that less than 10% of light detectable by the light detector is shunted light.

Abstract
A pulse oximeter sensor comprising an emitter and a detector disposed on a substrate layer with a thinned portion between the emitter and the detector. A partially transparent covering layer covers the substrate layer and comprises a corresponding thinned portion. The thinned portions attenuate light shunted via the substrate layer and the partially transparent covering layer from the emitter to the detector, and may be configured such that less than 10% of the light detectable by the detector is shunted light.
