Abstract
An electro-optical physiologic sensor comprises a printed circuit board (PCB) and a light emitter and a photodetector respectively mounted to the PCB. A first sensor element is disposed on the PCB and comprises a first electrode configured to contact tissue of a subject and a first light channel co-located with the first electrode, the first light channel optically coupled to the light emitter and configured to direct light into the subject's tissue. A second sensor element is disposed on the PCB and comprises a second electrode configured to contact the subject's tissue and a second light channel co-located with the second electrode, the second light channel optically coupled to the photodetector and configured to receive light from the tissue of the subject resulting from the light generated by the light emitter.
