摘要:
An optical pulse-rate sensor includes a fixture, a light emitter, a light sensor, and a light stop. The fixture has a rim configured to contact a skin surface and enclose an area of the surface. The light emitter and light sensor are each coupled to the fixture and positioned opposite the area. The light stop is coupled to the fixture and positioned between the light emitter and the light sensor to shield the light sensor from direct illumination by the light source.
