3RD GENERATION · TEXTILE WEARABLE ROBOTICS

The next form factor of wearable robots
is clothing

Wear Strength, Protect Life

SARTEXO builds active textile wearable robots powered by Fabric Muscle. Instead of motors, gearboxes and rigid frames, the fabric itself contracts to generate force.

THE EVOLUTION OF WEARABLE ROBOTICS

The evolution of wearable robotics

From 1st-gen machine, through 2nd-gen gear, to 3rd-gen clothing

The Bionic Suit Lineup

The fabric itself contracts to generate force. No motors, no frames — worn over workwear, or integrated into the workwear itself. Choose the joints you need, or integrate waist and upper body in one suit. Fabric Muscle, the core material, is also supplied as standalone actuators for research labs and corporate R&D.

INSIDE THE ROBOT

A completely different 3rd-gen form factor — the clothing itself is the robot

Not a back-support belt — an electrically controlled artificial muscle that generates real force.

  2. Power & ControlPower & ControlBattery and current control set how much force, and when
  3. Wearable StructureWearable StructureThe garment structure transfers Fabric Muscle's contraction force to the body
  4. Human AssistanceHuman AssistanceAssists movement at the waist, shoulder and elbow

Why SARTEXO

Why SARTEXO

To make a wearable robot you wear like clothing, we started over from the material.

  • Lightweight

    Light

    1.3 kg

    The weight of Bionic Suit Waist, including the battery and controller.

  • Frameless

    No motors, no frames

    No drive noise

    The fabric itself is the actuator, so there are no motors or gearboxes and no drive noise. With no frame or hinge, the structure does not constrain body movement.

  • Multi-joint

    Three joints in one suit

    World's first

    Bionic Suit Full is the world's first clothing-type suit to assist the waist, shoulder and elbow simultaneously — under 2 kg including battery and controller.

  • Built-in

    Worn over workwear, or integrated into the workwear itself

    Over-layer · Built-in

    Because fabric replaces motors and frames, the suit can be cut and sewn along designed patterns. The standard version goes over workwear; the built-in version is integrated into the workwear itself after reviewing the work motions and uniform design.

World's first simultaneous three-joint assistance: Korea Institute of Machinery & Materials press release, Oct 2025.

VALIDATION

Confirmed through testing and clinical research

In a waist-assistance evaluation with healthy adult workers, waist muscle activity fell by more than 40%.* The shoulder-assist suit has been used in clinical research at Seoul National University Hospital, and field trials are underway with the Republic of Korea Army Headquarters.

* Waist-assistance evaluation basis. Detailed conditions — evaluation model, load, and measurement metrics — are provided as documentation during consultation.
