1. A wrist-wearable device, comprising:
a first skin-contact portion of a band of the wrist-wearable device that:
(i) includes a first flexible printed circuit board,
(ii) is coupled with a first set of biopotential-signal sensors for detecting first biopotential signals that are provided to the first flexible printed circuit board, and
(iii) is coupled with an elastic material that extends beyond an end of the first skin-contact portion of the band and the elastic material is not directly coupled with the first-set of biopotential-signal sensors; and
a second skin-contact portion of the band of the wrist-wearable device that is separated from the first skin-contact portion of the band by a capsule structure, the second skin-contact portion:
(i) including a second flexible printed circuit board,
(ii) coupled with a second set of biopotential-signal sensors for detecting biopotential signals that are provided to the second flexible printed circuit board, and
(iii) coupled with a receiving loop for receiving the elastic material to affix the band to a body part of a wearer of the wrist-wearable device and the receiving loop is not directly coupled with the second set of biopotential-signal sensors,
wherein the first skin-contact portion and the second skin-contact portion are made of a same material that is distinct from the elastic material, such that when the wrist-wearable device is worn on the wrist of a user the elastic material is configured to stretch to affix the band to a wrist of the user through the receiving loop and the first and second skin-contact portions are not configured to stretch to thereby cause at least some of the first and second sets of biopotential-signal sensors to contact skin of the user.
