A noninvasive photoplethysmographic sensor platform for small animals provides a spring biased sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip face member. The saddle shape of the clip face member may have a hinge end, toward the hinge of the clip, which is longer in the longitudinal direction of the clip and shorter in depth than the distal end. The shorter distal end side (measured longitudinally) of this saddle shape facilitates the ability to align the transmitted and received light with the bone, while the overall saddle shape of the facing provides a physical grip to capture enough tissue to prevent the clip from relocating over time while it is attached to the limb. The shorter hinge end side (depth-wise) also allows the clip to close when it is fully assembled. The edges of the saddle shaped clip are preferably rounded off to prevent the contusions of the tissue that may result from long-term contact. This saddle faced feature works well on only one side of the clip.
