InteSpring
"Experts in Energy-Balancing-Solutions"
Dutch exoskeleton specialist (est. 2006, Rijswijk) using passive spring technology; creator of the Centaur military load-carrying exoskeleton with TNO.
InteSpring B.V. is a Dutch mechatronics company founded in 2006 by Boudewijn Wisse, Wouter van Dorsser, and Rogier Barents, headquartered in Rijswijk, South Holland, Netherlands. The company's core expertise is in energy-balancing solutions — systems that counterbalance gravitational forces using passive spring technology, gas springs, hydraulic accumulators, compliant structures, and magnetic springs. InteSpring holds patented technology for gravity-counterbalancing mechanisms, enabling lightweight and energy-efficient wearables and industrial devices without requiring external power.
The company's primary focus is on exoskeletons and medical orthoses that use purely mechanical spring systems to reduce physical load on the human body. InteSpring's flagship product is the Centaur, a semi-passive leg exoskeleton developed for military load-carrying applications. Designed in collaboration with the Dutch Ministry of Defence and research institute TNO under the Exobuddy project (spanning approximately 8 years), the Centaur allows a soldier to carry up to 60 kg of equipment while experiencing it as approximately 12 kg.
The device uses a hydraulic system activated by the natural walking motion, and incorporates AI-based prediction of when hydraulic systems need to be active. The Centaur was publicly presented at Eurosatory 2022. InteSpring is also connected to Laevo, a sister company that manufactures passive back-support exoskeletons for industrial workers in mobile environments where conventional back-support systems cannot be used.
InteSpring additionally develops the Hermes, a passive ankle orthosis for pes equinus (foot drop) used in home rehabilitation and modular physiotherapy. The company operates from multiple European locations with cross-location technical collaboration, combining deep domain expertise in spring mechanisms with embedded AI for motion analysis. Its address is Patrijsweg 24, 2289 EX Rijswijk, The Netherlands.
