Wearable ring device electrode design

A method for acquiring physiological data, comprising

• generating, using one of a first set of electrodes or a second set of electrodes of a wearable ring device, a first signal for transmission along a first signal path through at least a portion of a body of a user, wherein the first set of electrodes are positioned at least partially within a crown feature of the wearable ring device that extends from at least a portion of an outer housing of the wearable ring device, wherein the first set of electrodes define at least a portion of a first outer surface of the wearable ring device, wherein the first set of electrodes comprise two or more first electrodes, and wherein the second set of electrodes are positioned at least partially within an inner housing of the wearable ring device and comprise two or more second electrodes;
• measuring, using the other of the first set of electrodes or the second set of electrodes, the first signal received via the first signal path, wherein the first signal path is formed between the first set of electrodes and the second set of electrodes based at least in part on the user placing a first finger on the first set of electrodes and based at least in part on a second finger of the user contacting a second set of electrodes of the wearable ring device;
• and
• generating one or more physiological measurements of the user based at least in part on measuring the first signal.
