01An earlier exterior study
The ARC design combined a small horizontal pebble module, a flexible four-lobed carrier and a separate flattened hub, finished in pearl silver.
02Position: the back of the neck
ARC also sat at the back of the neck, with the attachment shaped around neck curvature, hair, collars and everyday movement.
03A replaceable carrier
Separating the reusable electronic module from the skin-contact carrier is a design direction. Sealing, cleaning, attachment reliability and the material system are still engineering questions.
