Abstract
A monitoring device includes a sensor band configured to be secured around an appendage of a subject, a sensing element secured to the sensor band, a second band configured to be secured to the appendage of the subject in adjacent, spaced-apart relationship with the sensor band, and at least one member connecting the sensor band and the second band. The sensor band has a first mass and the sensing element has a second mass that is less than the first mass. The sensing element is movably secured to the sensor band via a biasing element, and the biasing element is configured to urge the sensing element into contact with a portion of the appendage. The biasing element decouples motion of the sensor band from the sensing element, and the at least one member decouples motion between the sensor band and the second band.
