What It Is

A new category of wearable.

ARCH V1 is a wearable walking simulator worn just below the knee. It is not a compression device. It does not use electrical stimulation. It uses four micro linear actuators to mechanically replicate the calf muscle pump, the natural mechanism your legs activate during walking.

Designed exclusively for inactivity periods: seated work, long-haul travel, recovery. Not intended for use during active walking. Patented technology.

The Mechanism

Walking Cycle Technology.

Four micro linear servo actuators, vertically aligned over the calf. Each actuator moves independently, generating a coordinated pressure wave that alternates between negative and positive pressure phases.

Walking Cycle Technology

Mechanical from the ground up.

Four precision micro linear servo actuators, vertically aligned over the calf. The mechanism is entirely mechanical, driven by coordinated pressure waves that closely match the biomechanics of a walking step.

  • Quiet operation for shared spaces
  • Each actuator moves independently, not in unison
  • Activation triggered by ML, not a fixed timer
  • Compact form, single-hand adjustment

Real-Time Sensing

Three sensors. Continuous data.

Through direct skin contact, ARCH V1 monitors three physiological signals at all times. This data is the input for the ML system, which determines when and how to activate the Walking Cycle.

Bioimpedance Edema monitoring via bioelectrical impedance

On-Device Intelligence

Adaptive, not static.

ARCH V1 uses a two-layer ML architecture. System-level learning identifies inactivity patterns and physiological response over time. User-specific adaptation runs entirely on-device and on the paired phone. No personal data is transmitted to external servers.

On-Device Learning

Personalization runs locally. The device and your phone hold all adaptive data. Nothing leaves your device ecosystem.

Pattern Recognition

The system learns your individual inactivity patterns and physiological response, refining its activation timing over sessions.

On-Demand Activation

The device stays passive between active windows. The Walking Cycle triggers only when the ML determines it is appropriate, not on a fixed schedule.

Construction

Built with intention.

Skin-Contact Layer

Breathable nano-textile with integrated sensor windows. Allows continuous skin contact without adhesives or gel.

Actuator Tips

Silicone-based skin-conforming caps on each piston head. Each cap moves independently of the textile layer, adapting to leg contour.

Housing

Injection-molded plastic body with an aluminum front panel. Compact form designed to sit flush against the calf during use.

Strap

Nano-textile adjustable band. Structured where it needs to hold, flexible where it needs to move. Fine-grain adjustment for precision fit.

Designed For

For everyone who sits too much.

Desk Workers

For professionals spending long hours at a workstation. Deep focus sessions, back-to-back meetings, all-day desk work.

Frequent Travelers

For long-haul flights, airport gates, and extended transit. Designed to be compact enough for carry-on use.

Athletes in Recovery

For rest and recovery phases where active movement is reduced. Supports leg activity during stationary recovery periods.

Wellness-Oriented Users

For anyone building proactive wellness habits. Prevention-focused, not reaction-based.

Portability

Compact enough to take anywhere.

ARCH V1 is designed for real life. Compact enough to fit in a carry-on, quiet enough for shared spaces, and simple enough to put on and take off in seconds.

  • Quiet operation for open offices and cabins
  • Single-hand adjustment
  • USB-C charging, compatible with standard travel adapters
  • Available in Mineral Grey and Graphite Black
ARCH V1 portable use

ARCH ML App

The interface to your data.

Available on iOS and Android. The app visualizes your session data, processes sensor input for the adaptive ML system, and manages device settings.

  • Real-time sensor data visualization
  • Session feedback after each use
  • Adaptive personalization over time
  • Device control and manual override
  • Two devices connect and sync for bilateral use
  • Without the app, manual sessions are still possible

Sensor processing and adaptive ML require the app. Manual mode runs independently on the device.
