INTERMESHING LIGHT BARRIER FEATURES IN OPTICAL PHYSIOLOGICAL PARAMETER MEASUREMENT DEVICE

摘要

Light-blocking structures for optical physiological parameter measurement devices or sensors are disclosed. Such optical physiological parameter measurement devices or sensors may include two photodetectors and a photo-emitter, as well as barrier walls that are interposed between the photo-emitter and the photodetectors. The barrier walls may have recesses that intermesh with surface profiles of protrusions that are attached to or part of a window of the optical physiological parameter measurement devices or sensors.
