Wearable device with physiological parameters monitoring

A wearable device configured to perform physiological measurements, the wearable device comprising:

• a frame;
• an electrode secured to the frame and configured to conduct electrical signals originating from a user of the wearable device, the electrode comprising:
• a first portion having a surface configured to contact a skin of the user;
• a second portion having a surface configured to contact the skin of the user;
• a third portion disposed between the first portion and the second portion, the third portion comprising:
• a surface that extends away from the surface of the first portion and the surface of the second portion and is separated from the skin of the user when the first portion or the second portion contacts the skin of the user;
• and
• a through-hole extending through the electrode and configured to receive at least a portion of the frame, wherein a cover portion of the frame occludes the third portion from contacting the skin of the user;
• and
• an end portion adjacent to the first portion and extending away from the first portion at an angle;
• and
• a substrate in electrical connection with the electrode and responsive to the electrical signals originating from the user.
