Abstract

A physiological sensor is provided that includes an emitter and detector disposed on a frame such that the emitter and detector define an optical axis. The frame includes one or more pair of flexible elements disposed generally symmetric relative to the optical axis. In one embodiment, the emitter and detector remain aligned when moved relative to one another along the optical axis.
