MODULATED PHYSIOLOGICAL SENSOR
First Claim
1. A modulated physiological sensor is responsive to a physiological reaction of a living being to an internal or external perturbation that propagates to a surface area of the living being and is detected by a detector, the modulated physiological sensor comprising:
- a detector configured to communicate with a surface area of a living being so as to generate a signal responsive to a physiological reaction of the living being to a perturbation;
a modulator that varies the coupling of the detector to the surface area so as to at least intermittently maximize the detector signal; and
a monitor that controls the modulator and receives the detector signal so as to calculate a physiological parameter indicative of a physiological state of the living being.

Abstract
A modulated physiological sensor is a noninvasive device responsive to a physiological reaction of a living being to an internal or external perturbation that propagates to a skin surface area. The modulated physiological sensor has a detector configured to generate a signal responsive to the physiological reaction. A modulator varies the coupling of the detector to the skin so as to at least intermittently maximize the detector signal. A monitor controls the modulator and receives an effectively amplified detector signal, which is processed to calculate a physiological parameter indicative of the physiological reaction.
