SYSTEM AND METHODS FOR DETECTION AND REMOVAL OF ELECTRICAL NOISE IN DRY ELECTRODES

The present disclosure provides computer-implemented methods, systems, and devices for mitigating noise in a signal. A user computing device comprises physiological signal sensor configured to generate a first signal relating one or more characteristics associated with a user. The user computing device further comprises a transducer configured to generate a noise signature signal based on detection of one or more noise sources. The user computing device further comprises one or more control circuits configured to modify the first signal based on the noise signature signal to generate a modified first signal. The control circuits are further configured to determine one or more characteristics associated with a user based on the modified first signal.
