The electrode can comprise 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, and a third portion disposed between the first portion and the second portion. The third portion can comprise a through-hole extending through the electrode and that may receive at least a portion of the frame. A portion of the frame may occlude the third portion from contacting the skin of the user. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The wearable device of claim 1, wherein the end portion is enclosed by the frame. ### Claim 3 (depends on 1) The wearable device of claim 1, wherein the frame occludes the end portion from contacting the skin of the user. ### Claim 4 (depends on 1) The wearable device of claim 1, wherein a surface of the end portion does not contact the skin of the user. ### Claim 5 (depends on 1) The wearable device of claim 1, wherein the end portion is substantially orthogonal to the first portion. ### Claim 6 (depends on 1) The wearable device of claim 1, wherein the end portion comprises a through-opening extending through the end portion, the through-opening configured to receive a protrusion of the frame to secure the electrode to the frame. ### Claim 7 (depends on 1) The wearable device of claim 1, further comprising a fourth portion comprising: a surface that is continuous with the surface of the second portion, wherein the surface of the fourth portion extends away from the surface of the second portion and is separated from the skin of the user when the second portion contacts the skin of the user; and a second through-hole extending through the electrode and configured to receive an electrically conductive material configured to conduct the electrical signals originating from the user to the substrate. ### Claim 8 (depends on 7) The wearable device of claim 7, wherein a second cover portion of the frame occludes the fourth portion from contacting the skin of the user. ### Claim 9 (depends on 1) The wearable device of claim 1, further comprising: a fifth portion comprising a surface that is continuous with the surface of the fourth portion and configured to contact the skin of the user; and another end portion adjacent to the fifth portion, the another end portion having a surface that is continuous with the surface of the fifth portion, the another end portion extending from the fifth portion at an angle. ### Claim 10 (depends on 9) The wearable device of claim 9, wherein the another end portion comprises another through-opening extending through the another end portion, the another through-opening configured to receive another protrusion of the frame to secure the electrode to the frame. ### Claim 11 (depends on 1) The wearable device of claim 1, wherein the first portion is substantially semi-annular. ### Claim 12 (depends on 1) The wearable device of claim 1, wherein the first portion and the second portion form at least a portion of a semi-annulus. ### Claim 13 (depends on 1) The wearable device of claim 1, wherein the surface of the third portion is continuous with the surface of the first portion and the surface of the second portion. ### Claim 14 (depends on 1) The wearable device of claim 1, wherein the end portion comprises a surface that is continuous with the surface of the first portion. ### Claim 15 (depends on 1) The wearable device of claim 1, further comprising a hardware processor coupled to the substrate and configured to access the electrical signals conducted via the electrode. ### Claim 16 (depends on 15) The wearable device of claim 15, wherein the hardware processor is configured to perform one or more electrocardiography techniques with the electrical signals conducted via the electrode. ### Claim 17 (depends on 15) The wearable device of claim 15, wherein the hardware processor is configured to generate an electrocardiography (ECG) waveform from the electrical signals conducted via the electrode. ### Claim 18 (depends on 15) The wearable device of claim 15, wherein the hardware processor is configured to determine one or more cardiac conditions of the user based on at least the electrical signals conducted via the electrode. ### Claim 19 (depends on 1) The wearable device of claim 1, wherein the electrode is configured to secure to the frame without an adhesive. ### Claim at position 20 20-60.
