Futurewave’s Arc Silver Bracelet Uses a Gentle Vibration to Curb Phone Overuse

Belgian design studio Futurewave has introduced Arc, a silver bracelet designed to deliver a discreet physical signal when its wearer has spent too much time looking at a phone screen. Rather than adding another display or notification stream to an already crowded digital life, the concept strips wearable technology down to a single gesture: a gentle pulse that suggests, but does not force, a moment of disconnection.

Revealed in September 2026, Arc is currently a prototype that has undergone 3D-printed form studies and metal prototyping. No production timeline or retail launch has been announced. The project was developed by Hugo Simon, Pierre Heuson, Joachim Froment and the Futurewave team, based in Brussels.

How the bracelet works

The logic behind Arc is deliberately minimal. Through a companion portal accessed from a smartphone, the wearer selects a group of applications and sets a time limit — for example, 30 minutes of continuous use. Once that threshold is reached, the bracelet sends a short, clear vibration through its metal structure and into the wrist. If the wearer continues using the phone, a second identical pulse follows. After that, the device falls silent and resets for a new interval.

There are no notifications to dismiss, no apps to block, no usage statistics to review. According to Futurewave, the system keeps no history of how the bracelet was used, requires no user account, and involves no subscription. The intention is to create a gentle boundary rather than a punitive lockout.

A jewelry-first approach to wearables

Arc’s form draws from the ancient torc — an open metal collar or bracelet associated with European Iron Age cultures — and its rounded, interconnected volumes were inspired by anatomical and natural structures such as rib cages, wishbones, hydroids and chains of seed pods. The result is a continuous, sculptural shape that wraps around the wrist without a clasp, hinge or visible fastening. The design is intentionally gender-neutral, emphasising material and form over conventional jewellery categories.

The bracelet is designed to be shell-cast in Argentium silver, an alloy chosen for its premium character and tarnish resistance. The development process included 3D-printed form studies that evolved from simple circular bands to more elaborate beaded and lobed surfaces, as well as prototypes in stainless steel and titanium.

Technology hidden inside the metal

All electronic components are concealed within the flowing metal structure. A piezoelectric element generates the tactile signals, selected for its ability to produce a clearly defined pulse. An ONiO zero low-power microcontroller manages the Bluetooth Low Energy connection to the phone, while a flexible circuit board follows the bracelet’s curvature. A 25 mAh curved battery, charging circuitry and piezoelectric energy harvesting complete the system. None of these components are visible from the outside.

The bracelet has no display, no speaker and no illuminated indicators. Communication happens exclusively through touch, leaving the surrounding environment to provide visual stimulation.

A stance on obsolescence

The project also raises a question about the relationship between luxury objects and technological obsolescence. ‘Jewellery first, one gesture inside it, and nothing kept,’ explains Cédric de Bellefroid, co-founder and CEO of Futurewave. The studio imagines a product whose value does not depend entirely on the lifespan of its electronics: once the technology stops working, the silver bracelet can simply remain a bracelet.

This approach contrasts with most connected devices, which become e-waste when their software or battery fails. Arc proposes a wearable that remains physically and aesthetically compelling even when its digital function is no longer active.

What it means for digital wellness

Arc enters a growing category of tools designed to address smartphone overuse, but it does so without adding more data or screen time. By relying on a single tactile signal and no feedback loop, it avoids the gamification and anxiety that can accompany usage-tracking apps. The bracelet offers a reminder, not a report.

For architects, designers and urbanists — the core readership of this site — the project is notable as an example of how wearable technology can be rethought through material culture and product design rather than software alone. It suggests that a connected object’s value may lie as much in its physical presence and longevity as in its digital function.
