Exoskeleton: definition, types, uses and prices (2026 guide)

The word "exoskeleton" brings to mind an insect's shell, Iron Man's armour or a patient walking again in a rehabilitation centre. Over the past few years it has also come to mean real equipment you can buy: a motorised belt for hiking, a spring-loaded knee brace for skiing or a harness that takes the strain off a warehouse worker's back. This guide explains what an exoskeleton really is, how it works, what it is used for, how much it costs and what it cannot do, using the real prices in our catalogue and official sources.

The essentials in 30 seconds

• Definition: an exoskeleton is a structure worn on the body that assists a movement or relieves a joint, using springs, cables or motors.
• Three worlds: medical (rehabilitation, on prescription), occupational (preventing musculoskeletal disorders) and sport and leisure (walking, hiking, skiing).
• Three mechanisms: passive (springs), active (motors and a battery) and soft (cables and technical fabrics).
• Price: from €192 for a support legging to €4,200 for an occupational shoulder exoskeleton; a motorised walking model costs from $689 to around €2,000.
• Limits: it is neither a treatment nor a suit of armour. A sports exoskeleton is generally not reimbursed, and France's occupational health institute (INRS) points out that it can create new risks if it is poorly chosen or poorly introduced.

What is an exoskeleton?

An exoskeleton is a device worn on the outside of the body, on the back, hips, legs or arms, that accompanies a movement to reduce the effort involved or to relieve a joint. It works with the body: it does not replace the muscles, it takes part of the load off them, or adds strength at the right moment.

The term comes from biology. In insects, spiders and crustaceans, the exoskeleton is the external skeleton, the rigid shell that protects the animal and to which its muscles are attached. Engineers borrowed the image: a mechanical "shell" worn over the human body.

The INRS, France's reference body for occupational health and safety, places exoskeletons within a wider family of physical assistance technologies, alongside collaborative robots and load-carrying harnesses. Its definition stresses one point: an exoskeleton is worn by the person and acts on their movements, which sets it apart from a machine that does the work instead of them.

Fabric models without a rigid frame are called soft exoskeletons or "exosuits". The line between them and support garments is thin: we explain it in our question on the difference between an exoskeleton and a textile exosuit.

Where does the exoskeleton come from? A short history

• 1890: engineer Nicholas Yagn files a US patent for a device meant to make walking, running and jumping easier, often cited as the first exoskeleton project.
• 1960s: General Electric and the US military work on the Hardiman, a giant exoskeleton weighing several hundred kilos and designed to lift heavy loads. The prototype never became fully operational.
• 2000s: in Japan, Cyberdyne develops HAL, which picks up the electrical signals of the muscles to trigger assistance. Medical exoskeletons enter rehabilitation centres.
• 2014: ReWalk becomes the first exoskeleton cleared in the United States for personal use by people with paraplegia.
• 2010s: passive exoskeletons spread through industry and logistics to prevent musculoskeletal disorders; in France, the NF X35-800 standard has governed their introduction in companies since 2022.
• Since 2023: motorised consumer exoskeletons for walking and hiking arrive (Hypershell, Dnsys, VIGX), sold online for around €1,000.

On the defence side, the big "powered armour" programmes have mostly stayed at the prototype stage: we sort fact from fiction in our article military exoskeletons, science fiction or reality.

How does an exoskeleton work?

All exoskeletons share the same principle: shifting part of the effort from one area of the body to another, or to an external energy source. What changes is the mechanism.

1. The spring (passive exoskeleton): it stores energy as you bend, then releases it as you straighten up. No battery, no motor. This is how the Ski-Mojo works for skiing, as do the Hapo exoskeletons for the back and shoulders.
2. The motor and sensors (active exoskeleton): sensors detect your movement and a battery-powered motor adds force at the right moment. This is the case for the Hypershell, Dnsys and VIGX walking models, which assist the hip with every step.
3. The cable and the fabric (soft exoskeleton): elastic bands and tensioned cables guide and support the joint without adding energy. Example: the Stoko K1 tight for the knee.

Each mechanism has its strengths: passive is light, simple and needs no charging; active provides real extra force but is heavier and depends on its battery; textile can be worn all day but offers little assistance. The details are in our article how does an exoskeleton actually work, and the full comparison in our guide active exoskeleton or biomechanical support.

The main types of exoskeleton

Exoskeletons are classified in two ways: by use (for whom and for what) and by the part of the body they assist.

Use	For whom	Examples	Access
Medical	People with paralysis or in rehabilitation (spinal cord injury, stroke)	HAL (Cyberdyne), ReWalk, Ekso	Rehabilitation centres, on prescription
Occupational	Workers exposed to musculoskeletal disorders (construction, logistics, care)	Hapo, Laevo, Ottobock Paexo	Bought by the employer as part of a prevention plan
Sport and leisure	Hikers, skiers, athletes, active seniors	Hypershell, Dnsys, Ski-Mojo, Stoko	Sold online to the public

By part of the body, there are:

• hip exoskeletons, which assist walking and climbing (most motorised consumer models);
• knee exoskeletons, for skiing, osteoarthritis or descents: see our knee exoskeleton guide;
• back (lumbar) exoskeletons, which relieve the back when bending and carrying loads;
• shoulder and arm exoskeletons, for overhead work or work in front of the body;
• neck exoskeletons, for work with the head tilted back: see our neck exoskeleton guide;
• full-body exoskeletons, reserved for medical use or research.

To find out which brands make what, see our overview of exoskeleton brands in 2026.

What is an exoskeleton used for?

Walking further and hiking

This is the fastest-growing consumer use. A motorised walking exoskeleton is worn at the waist and on the thighs; it helps the hip with every step, especially on climbs and stairs. Manufacturers claim a lower perceived effort, which you should check against your own profile. To choose, read our comparison Hypershell or Dnsys, our article hiking exoskeleton, revolution or gadget and our question on real-world range when hiking.

Skiing without ending the day with burning knees

The Ski-Mojo, a passive spring exoskeleton, transfers part of the body's weight from the knees to the ski boots. It is aimed at skiers whose thighs or knees tire quickly. See our complete ski exoskeleton guide.

Relieving the knee, including osteoarthritis

Cable tights, springs or motorised modules: several solutions exist to relieve a painful knee during exercise. None of them cures osteoarthritis, and studies remain few. We read them for you in exoskeletons and knee osteoarthritis: what the studies show.

Protecting the back and shoulders at work

In construction, logistics or care work, an occupational exoskeleton reduces the load on the back, shoulders or neck during repetitive movements. It is part of a musculoskeletal disorder prevention plan and does not replace workstation design. See our guides by job: construction sites, manual handling, nurses and caregivers, warehouse workers, and our article on back pain at work.

Rehabilitation and walking again: the medical exoskeleton

In rehabilitation centres, exoskeletons such as HAL, ReWalk or Ekso help patients with a spinal cord injury or a stroke to stand and walk, under medical supervision. They are medical devices that cannot be ordered online for personal use without follow-up: we present them in medical exoskeletons: what are HAL, ReWalk and Ekso used for.

Staying independent with age

After 60, a lightweight walking exoskeleton can help you keep walking longer distances, provided you choose the right model and talk to your doctor if you have a medical condition. See our article walking longer after 60.

How much does an exoskeleton cost?

An exoskeleton costs from under €200 to over €4,000 for consumer and occupational models. Medical rehabilitation exoskeletons are sold on quotation to healthcare facilities. Here are the price ranges in our catalogue in October 2026, excluding promotions.

Family	Examples	Listed prices
Support garments (textile)	Imbrace Gen 2, Stoko K1	€192 to $388
Spring ski exoskeleton	Ski-Mojo	€699
Motorised walking (hip)	Dnsys X1 Lite, Hypershell Go X, VIGX π, Hypershell Ultra X	$689 to €1,999
Motorised hip and knee	Dnsys X1 Carbon + Z1, VIGX Ant-H1 Pro	$1,598 to $2,399
Occupational (back, shoulders, neck)	Hapo NECK, Hapo HD, Hapo UP	€640.80 to €4,200
Medical (rehabilitation)	HAL, ReWalk, Ekso	On quotation, no public price

What drives the price up: motorisation (motor, sensors, battery), materials (carbon fibre, titanium) and specialisation. Also budget for shipping and customs on products sold in dollars (see our question on taxes and customs). The details are in our article exoskeleton prices: how much does it really cost.

Is an exoskeleton reimbursed?

For an individual, as a rule, no. In France, the national health insurance only reimburses products on its list of reimbursable products and services (LPP), and we found no sports or leisure exoskeleton on it. Some supplementary insurers offer allowances for medical equipment: ask them directly. Details in our question on reimbursement by health insurance.

For a company it is different: the employer pays for the equipment as part of prevention, and public aid to reduce musculoskeletal disorders may be available. See financial aid for companies and who pays for an exoskeleton at work.

Who can use an exoskeleton?

• Athletes and hikers who want to go further or spare their joints.
• Skiers whose knees or thighs limit the length of their days.
• Workers exposed to awkward postures or load carrying, as part of a prevention plan approved by the employer and the occupational physician (see medical fitness).
• Active seniors who want to keep walking for a long time.
• Patients in rehabilitation, only with medical devices and under supervision.

As for body shape, consumer models usually adjust to a range of heights and waist sizes: check the manufacturer's chart (see choosing the right size and exoskeletons and women's body shapes). If you have a medical condition, a prosthesis or recent surgery, always ask your doctor before using one.

Advantages and disadvantages of an exoskeleton

Advantages	Disadvantages
Reduces the effort or load on a targeted joint	High price, rarely reimbursed
Lets you keep going longer (walking, skiing, at a workstation)	Weight to carry: about 0.5 kg for a tight, nearly 2 kg for a motorised model
Passive models need no charging and no electronics	Limited range and charging for motorised models
Can help you resume an activity after a dip in fitness, with medical advice	Adaptation period, possible discomfort, assistance limited to one movement
Prevents musculoskeletal disorders at work	New risks flagged by the INRS: load shifted elsewhere, falls, fatigue

Two concerns come up often: muscle loss and long-term effects. We reviewed the INRS work in our questions does an exoskeleton weaken muscles and what we know about long-term effects. And to separate fact from fiction, read our 6 exoskeleton myths, put to the test.

How to choose an exoskeleton

1. Start from the use, not the product: walking, skiing, knee, work? Each use has its own family.
2. Identify the area to relieve: hip, knee, back, shoulders. If you are torn between hip and knee, see hip or knee exoskeleton.
3. Choose the mechanism: passive if you want something light with no charging, active if you need real extra force (see active, passive or textile).
4. Set a realistic budget, including shipping and any customs fees.
5. Check size, weight, range, warranty and returns (see warranty and right of withdrawal).

For a first purchase, our question which first exoskeleton to choose sums up the best entry points. To compare models side by side, use our 2026 exoskeleton comparison or our interactive comparison tool.

Where to buy or try an exoskeleton

Consumer exoskeletons are mostly sold online, on manufacturers' or resellers' websites, and sometimes in sports shops. Our exoskeleton selection brings together the models we follow, by brand, with detailed product pages. Before buying:

• Try one if you can: rental, demonstrations at trade shows or ski resorts. See renting an exoskeleton before buying.
• Check the seller: legal notice, return policy, after-sales service in Europe. See how to check a website is reliable.
• For a company, follow an integration process with trials on the real workstation (see the NF X35-800 method).

Frequently asked questions

What is an exoskeleton?

An exoskeleton is a device worn on the body (hips, legs, back or arms) that assists a movement or relieves a joint, using springs, cables or motors. There are medical models for rehabilitation, occupational models to prevent musculoskeletal disorders and consumer models for walking, hiking or skiing.

How much does an exoskeleton cost?

From €192 for a support legging to €4,200 for an occupational shoulder exoskeleton, at the prices in our catalogue in October 2026. A spring ski exoskeleton costs €699 and a motorised walking exoskeleton from $689 to around €2,000. Medical rehabilitation models are sold on quotation to healthcare facilities.

Who can benefit from an exoskeleton?

Hikers, skiers and athletes who want to spare their joints, active seniors, workers exposed to awkward postures as part of a prevention plan, and patients in rehabilitation using supervised medical devices. If you have a medical condition or have had surgery, a doctor's advice is essential before any use.

What is the role of an exoskeleton?

Its role is to reduce the effort or load on part of the body: relieving the back when bending, helping the hip with every step, unloading the knees when skiing or helping a patient stand up again in rehabilitation. It assists the muscles without replacing them.

What are the disadvantages of an exoskeleton?

The price, the weight to carry, the limited range of motorised models, an adaptation period and assistance limited to certain movements. At work, the INRS also flags new risks: load shifted to other parts of the body, restricted movement, risk of falling or extra fatigue if the equipment is poorly suited to the task.

Is an exoskeleton covered by health insurance?

As a rule, no for sports, leisure or work models bought by an individual: in France, we found none on the LPP list of reimbursable products. Medical exoskeletons are used in rehabilitation centres as part of care. At work, the employer pays for the equipment.

Are there exoskeletons for consumers?

Yes. Since around 2023, motorised walking exoskeletons such as those from Hypershell, Dnsys or VIGX have been sold online to the public, alongside passive ski models such as the Ski-Mojo and support garments such as the Stoko K1.
