摘要:
Methods and apparatus are presented for removing motion artifacts from physiological signals produced by a physiological sensor of a wearable device, wherein the physiological sensor includes at least one optical emitter and at least one optical detector. Light emitted by the at least one optical emitter that is scattered by a body of a subject wearing the device is detected, and a physiological information signal therefrom is produced via the at least one optical detector. Light emitted by the at least one optical emitter that is scattered by a light regulating region of the wearable device is detected, and a motion noise information signal is produced via the at least one optical detector. The physiological information signal and the motion noise information signal are processed via at least one processor associated with the wearable device to at least partially remove unwanted motion artifacts from the physiological information signal.
