First Claim
1. An apparatus for sensing and measuring at least one physiological parameter of a person, the apparatus comprising:
- at least a portion of the apparatus configured for contacting a targeted tissue region;
an optical sensor comprising at least one light source for illuminating the targeted tissue region and at least one optical detector for receiving optical energy reflected from the targeted tissue region, the at least one light source and the at least one optical detector being coupled to a substrate,at least one lens associated with the at least one light source that directs light to the targeted tissue region;
at least one lens associated with the at least one optical detector that passes light reflected from the targeted tissue region; and
at least one barrier optically separating the at least one light source and the at least one optical detector wherein the at least one barrier is “
T-shaped” and
comprises a laterally-extending portion coupled to the substrate and a vertically-extending portion extending from the laterally-extending portion toward the targeted tissue region, the laterally-extending portion and the vertically-extending portion each optically separating the at least one light source and the at least one optical detector,wherein each lens is located in the portion of the apparatus contacting the targeted tissue region.

Abstract
Described herein are systems and methods for mounting optical sensors in a physiological monitoring device worn by a user to sense, measure, communicate, and/or display physiological information. The monitoring devices may be embodied as, for example, a fitness band, a bracelet, a watch, or some other wearable device such as an activity tracker, a health, wellness, or sleep monitor, or an athletic training device. The device may comprise one or more light sources and optical detectors. Optical lenses may be mounted in a face of the device for partially receiving or containing the light sources and optical detectors. The devices and methods described herein may optically isolate the light source(s) from the optical detector(s) to ensure the accurate and reliable detection and measurement of physiological information.
