    Abstract: An optoelectronic biosensor includes a housing with a transparent support surface. The optoelectronic biosensor also includes an emitter device in a first region of the housing adapted to generate and emit light toward the support surface. The optoelectronic biosensor further includes a detector device in a second region of the housing. The optoelectronic biosensor additionally includes a first optical fiber element between the detector device and the support surface. The first optical fiber element is configured to guide light incident on the support surface at an angle less than a predetermined angle to a normal to the detector device. The predetermined angle depends at least on a difference in refractive indices at an interface between the optical fiber element and a material surrounding the optical light guide element. A material of the first region surrounding the emitter device is the same as the material surrounding the first optical fiber element.

    Abstract: A noninvasive physiological sensor can include a first body portion and a second body portion coupled to each other and configured to at least partially enclose a user's finger. The sensor can further include a first probe coupled to one or more emitters and a second probe coupled to a detector. The first probe can direct light emitted from the one or more emitters toward tissue of the user's finger and the second probe can direct light attenuated through the tissue to the detector. The first and second probes can be coupled to the first and second body portions such that when the first and second body portions are rotated with respect to one another, ends of the first and second probes can be moved in a direction towards one another to compress the tissue of the user's finger.
