Passive or Active Exoskeletons — How to Choose the Right Type
Industrial exoskeletons come in two main types: passive — operating without power through springs and mechanical elements — and active — driven by motors, sensors, and batteries. Understanding the difference is the first step toward selecting the right device for a specific task and working environment.
Passive Exoskeletons
Passive exoskeletons use springs, elastic elements, or carbon rods to redistribute load away from vulnerable body zones. No motors, no batteries, no electronics.
Specifications:
- Weight: 1.0 – 4.5 kg
- Autonomy: unlimited — full shift wear
- Maintenance: minimal
- Price: 1,000 – 3,500 EUR
- Certification: EU PPE Regulation 2016/425
Best suited for: Repetitive tasks with moderate load — lifting, forward bending, overhead work, assembly lines, logistics and warehousing.
Active Exoskeletons
Active exoskeletons use electric motors or pneumatics, controlled by real-time sensors. They generate assistive force to compensate for loads beyond the reach of passive systems.
Specifications:
- Weight: 5 – 8 kg
- Autonomy: 4 – 8 hours per charge
- Maintenance: regular — battery, software updates, servicing
- Price: from 8,000 EUR
- Assistive force: up to 15 kg active support
Best suited for: High-intensity tasks where passive support is insufficient — heavy lifting, prolonged work at maximum physical load.

| Price | 1,000 – 3,500 EUR | from 8,000 EUR |
| Maintenance | Minimal | Regular |
| Deployment | Fast | More complex |
| PPE certification | Yes | Model-dependent |
How to Choose the Right Type
The choice is not between “better” and “worse” — it is about matching the device to the task. Three questions help narrow it down:
1
What is the load intensity?
Moderate, repetitive load — passive. High-intensity load that exceeds passive support capacity — active.
2
How long is the device worn per shift?
Passive exoskeletons have no autonomy constraints. Active models require charging — shifts over 8 hours may require a spare battery.
3
What is the working environment?
Moisture, dust, extreme temperatures — passive models are more robust with no infrastructure requirements. Active models require charging stations and access to servicing.
The rule: an exoskeleton is never chosen by price or brand — it is chosen by task. A wrongly selected model not only fails to help — it can restrict movement and increase risk.
Can They Be Combined
Yes. In real production environments, the two types are not mutually exclusive. A common scenario: an active exoskeleton for the most physically demanding tasks of the shift, a passive model for everything else. ExoPower assesses your specific workplaces and recommends the right combination.
What ExoPower Offers
ExoPower distributes and implements only certified exoskeletons from leading European manufacturers — Comau, Hapo, Auxivo, and ExoIQ. All passive models carry EU PPE certification under Regulation (EU) 2016/425, valid across every EU member state.
Exoskeletons manufactured outside the EU are typically not registered as PPE and may not meet European workplace safety requirements.
Frequently Asked Questions
Is an active exoskeleton better than a passive one?
Not inherently — it is only more appropriate when the task demands it. For repetitive tasks with moderate load, passive models are more practical, lighter, and significantly cheaper to deploy and maintain.
Can a passive exoskeleton be worn for an entire shift?
Yes. Passive models are designed for continuous wear with no autonomy restrictions.
How quickly does an active exoskeleton deliver ROI?
With the right model matched to the task, ROI typically occurs within 12–18 months through reduced sick leave, fewer workplace injuries, and improved productivity.
Do active exoskeletons require specialist training?
Yes. Active systems require more in-depth training for both operators and technical staff compared to passive models. ExoPower includes training as part of the implementation process.
What happens if the battery runs out mid-shift?
Most active models switch to a passive mode when the battery is depleted. For shifts exceeding 6 hours, a spare battery is recommended.
How do I know which type is right for my operation?
ExoPower conducts on-site workplace assessments – we analyse movements, load levels, and environment before recommending a specific model.
