DYNAMICALLY ADJUSTABLE BANDS FOR WEARABLE DEVICES

Bands for electronic devices, including wearable devices, are designed to dynamically alter their shape (e.g., lengthen) in response to an external force. A band may include one or more interior structures disposed in an exterior structure. The interior structure(s) is/are pulled in tension by the exterior structure. When the interior structure(s) is/are pulled in tension, an additional force (e.g., by a user) that applies tension to the interior structure(s) may cause a relatively small change in tension to the interior structure(s). As a result, the band may appear to provide the same amount to users, despite users having a different wrist size/diameter. A similar phenomenon may occur to a single user when the user's wrist changes in size. Accordingly, based on the interior structure(s) being placed in tension by the exterior structure(s), the force provided by the band may appear constant to users.
