Physiological Monitoring Devices Having Sensing Elements Decoupled from Body Motion

摘要

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.

1. A monitoring device, comprising:
a biasing element having opposite first and second end portions; and a sensing element attached to the biasing element second end portion, wherein the monitoring device is configured to be attached within a portion of an ear of a subject such that the biasing element first end portion engages the ear at a first location and such that the sensing element is urged by the biasing member into contact with the ear at a second location.
