1. A noninvasive physiological sensor comprising:
a first probe and a second probe at least partially aligned with the first probe, the first probe coupled to one or more emitters and to at least one of a first and second body portions, the first probe configured to direct optical radiation emitted from the one or more emitters toward tissue of a user's finger, the second probe coupled to one or more detectors and to at least one of the first and second body portions, the second probe configured to direct light attenuated through pulsatile blood flowing through the tissue to the one or more detectors; and
the second body portion coupled to the first body portion about a joint, the first and second body portions configured to at least partially enclose the user's finger, the first or second body portion comprising:
a first arm extending from a first side of the first or second body portion and configured to movably couple the first probe to the first body portion; and
a second arm extending from a second side of the first or second body portion and configured to movable couple the second probe to the first body portion;
wherein, when the first and second body portions are rotated about the joint to a first position, the first or second arm apply a force to move the first and second probes towards each other and compress a tissue of the user's finger between the first and second probes.
