"3/4 view of multiple futuristic smart bands, arranged neatly on a neutral background. Each band has a unique, minimalist design without screens, showcasing various innovative surface textures. Some bands feature smooth, matte finishes; others have subtle ridges, geometric patterns, fine grooves, or embossed designs for a tactile and high-tech look. The materials appear premium, with slight metallic or ceramic-like sheens in muted tones like dark gray, silver, and charcoal. The aesthetic is modern and sophisticated, highlighting the individuality of each band through texture and form rather than digital displays.
