Claim 9:
10. A method of obtaining at least one bodily function measurement, comprising:
receiving, via a multifunction contact button of a wearable device, user input to interact with the wearable device, the wearable device comprising:
an outer body shaped as a part of a wristwatch and configured to be wearable on a wrist adjacent to a first hand of a user; and
a plurality of sensors, a first sensor of the plurality of sensors comprising a first electrode physically coupled to the outer body, the first electrode positioned to be contacted by the wrist of the user;
wherein the multifunction contact button comprises a second electrode of the first sensor, and wherein the multifunction contact button is coupled to the outer body and positioned to be contacted by a finger or thumb of a second hand of the user;

providing, based on the user input, information to initiate a transition of the wearable device from a normal course of operation to a measurement mode and to initiate an electrocardiogram (ECG) measurement, wherein the wearable device is configured to obtain photoplethysmography (PPG) measurements in the normal course of operation; and
obtaining, by a processor in response to the wearable device transitioning to the measurement mode, one or more ECG measurements based on signals received from the first electrode and the second electrode, one or more PPG measurements based on signals received from a second sensor of the plurality of sensors, or a combination thereof, the processor being contained within the outer body and communicatively coupled to the plurality of sensors.
