Abstract

Provided according to embodiments of the invention are systems for monitoring a physiological state of an individual that include a PPG sensor, which optionally includes an auxiliary physiological sensor integrated with or connected thereto; a first signal processing device in electronic communication with the PPG sensor, whereby the PPG sensor transmits PPG signals to the first signal processing device; and a second signal processing device that detects at least a portion of the signals transmitted by the PPG sensor to the first signal processing device, at least a portion of signals transmitted by the auxiliary physiological sensor, or both. Related methods are also provided herein.
