Systems and Methods for Monitoring Sleep Based on Surface Biopotentials

A method for monitoring sleep, the method comprising:

• obtaining, by a plurality of electrodes disposed on an interior of a wearable device worn on a portion of an arm of a user while the user sleeps, biopotential signals from the user's arm;
• analyzing, by a processor, biopotential data derived from the biopotential signals to determine one or more characteristics relating to sleep of the user;
• and
• generating, by the processor, an output based on the one or more characteristics relating to the sleep of the user.

A system for monitoring sleep, the system comprising:

• a wearable device configured to be worn on a portion of an arm of a user while the user sleeps, the wearable device comprising:
• a plurality of electrodes disposed on an interior of the wearable device and configured to obtain biopotential signals from the user's arm;
• and
• a processor configured to:
• analyze biopotential data derived from the biopotential signals to determine whether the user is asleep or awake;
• and
• generate an output based on the determination of whether the user is asleep or awake.
