Patent Images
1. A sensor comprising:
- a light source;
a light detector in optical communication with said light source; and
a sensor pad having a first surface and a second surface and the sensor pad at least partially housing said light source and said light detector,wherein the first surface is at least partially coated with a conductive adhesive and the second surface is at least partially coated with a pressure sensitive adhesive, wherein a thickness of said sensor pad is configured to capacitively isolate the light detector from a patient.

Abstract
A physiological sensor having reduced sensitivity to interference includes a light source, a light detector in optical communication with the light source, and a sensor pad at least partially housing the light source and the light detector. The sensor pad is configured to be capacitively isolated from a patient. Moreover, the physiological sensor may be electrically connected to an amplifier having a signal ground and a monitor.
