Breathable physiological sensor

摘要

A sensor includes a sensor pad that allows air and moisture to diffuse from a patient's skin. A light source is disposed on the sensor pad is configured to generate near-infrared light. A light detector disposed on the sensor pad is configured to detect near-infrared light generated by the light source.

主权项

1. A sensor comprising:
a sensor pad having a bottom surface configured to be applied to a patient and a top surface opposite said bottom surface, wherein at least a portion of said sensor pad is formed from a breathable material in a configuration such that air and moisture diffuse laterally from said sensor pad at a rate greater than any diffusion of air and moisture through said top surface; a light source disposed on the sensor pad and configured to generate near-infrared light; and a light detector disposed on the sensor pad and configured to detect near-infrared light generated by the light source.
