Wearable device for monitoring fluid overload with built-in sensors

A wearable device for monitoring a tissue swelling condition of a user, comprising:

• a device attachment mechanism for securing the wearable device to a body of the user;
• a sensing mechanism coupled to the device attachment mechanism, the sensing mechanism configured to provide an electrical signal in accordance with the tissue swelling condition;
• and
• a console including one or more processors and logic, that, upon execution by the one or more processors, causes performance of operations including:
• receiving the electrical signal from the sensing mechanism, and
• providing swelling information to the user in accordance with the electrical signal,
• wherein the device attachment mechanism comprises:
• a light sensor operatively coupled with a light source, and
• a variable aperture disposed between the light source and the light sensor, wherein:
• the variable aperture varies in accordance with a length of a stretchable portion of the device attachment mechanism, and
• the light sensor provides the electrical signal in accordance with an amount of light from the light source passing through the variable aperture to the light sensor.
