Abstract
A monitoring device includes a biasing element having opposite first and second end portions, an earbud attached to the biasing element first end portion, and a sensing element attached to the biasing element second end portion. The earbud has a first mass, and the sensing element has a second mass that is less than the first mass. The biasing element is configured to urge the sensing element into contact with a portion of the ear when the earbud is inserted into the ear. The biasing element decouples motion of the earbud from the sensing element. The sensing element includes at least one energy emitter configured to direct energy at a target region of the ear and at least one detector configured to detect an energy response signal from the target region or a region adjacent the target region.
