Abstract
An ear sensor provides a sensor body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The sensor body is flexed so as to position the housing over a concha site. The sensor body is unflexed so as to attach the housing to the concha site and position the optical assembly to illuminate the concha site. The optical assembly is configured to transmit optical radiation into concha site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.
