Exoskeleton motorized knees help soldiers carry heavy gear

Founded in 2010, B-TEMIA is a privately-owned dermoskeletic technology company. Based in Quebec City, Canada, B-TEMIA develops, manufactures and commercializes cutting-edge products in the growing market of human augmentation systems.

B-TEMIA’s proprietary wearable Dermoskeleton™ technology provides the user with robotized mechanical support to restore, maintain or enhance the mobility of users, with applications in the medical, industrial and military fields.

Using high-end sensors and advanced artificial intelligence proprietary software, the Dermoskeleton™ senses the user’s mobility intentions and generates synchronized movements at the motorized knees. The robotic system does not move for the user – instead, it senses the intended movement and provides the right level of assistance in perfect symbiosis with the body motion.

Acting as a secondary artificial musculo-skeletal structure surrounding the body, the Dermoskeleton™ can protect the wearer against extreme activities, and prevent acute or chronic musculo-skeletal injuries while increasing strength, endurance and stability.

A recent study conducted by the University of Michigan Human Neuromechanics Laboratory suggests that motion assisting exoskeleton utilizing the Knee-Stress Relief Device (K-SRD) can help battle-equipped soldiers to better perform in inclined terrain. K-SRD is part of the FORTIS system, the latest exoskeleton developed by on inclined terrain. K-SRD uses Dermoskeleton technology licensed from Canadian developer B-TEMIA. The system assists its wearer in completing repetitive or physically demanding tasks, such as lifting or dragging heavy loads, holding tools or equipment, repetitive or continuous kneeling or squatting, walking with load, walking up or downhill, and using stairs while carrying loads.

Four trained participants used the exoskeleton carrying 40-pound backpacks while walking at various speeds on a treadmill inclined to 15 degrees. The tests results show all participants conserved energy using the K-SRD, reducing overall exertion.
