Wearable light-guiding devices for physiological monitoring

摘要

A monitoring device configured to be attached to the body of a subject includes an outer layer and an inner layer secured together. The inner layer includes light transmissive material and has inner and outer surfaces. A base is secured to at least one of the outer and inner layers and includes an optical emitter and optical detector. A layer of cladding material is positioned near the outer surface of the inner layer, and at least one window is formed in the layer of cladding material that serves as a light-guiding interface to the body of the subject. The light transmissive material delivers light from the optical emitter to the body of the subject along a first direction and collects light from the body of the subject and delivers the collected light in a second direction to the optical detector. The first and second directions are substantially parallel.

1. A monitoring device configured to be attached to the body of a subject, comprising:
an outer layer and an inner layer secured together, the inner layer comprising light transmissive material, and having inner and outer surfaces; a base secured to at least one of the outer and inner layers and comprising at least one optical emitter and at least one optical detector; a layer of cladding material near the outer surface of the inner layer; and at least one window formed in the layer of cladding material that serves as a light-guiding interface to the body of the subject, wherein the light transmissive material is in optical communication with the at least one optical emitter and the at least one optical detector, wherein the light transmissive material is configured to deliver light from the at least one optical emitter to the body of the subject along a first direction and to collect light from the body of the subject and deliver the collected light in a second direction to the at least one optical detector, wherein the first and second directions are substantially parallel.
