Chinese Exoskeleton Z1: How the Device Reduces Knee Load by 200%.

The Chinese startup Dnsys has introduced the knee exoskeleton Z1, which, according to the developers, enhances muscle strength of the calves and thighs by 50%, while simultaneously reducing knee load by 200%. The product appeared on the crowdfunding platform Kickstarter. Z1 consists of two exoskeletons that are stored in a backpack and attached to the legs in 15 seconds. Each exoskeleton has a built-in electric motor and helps lift the thighs forward and push the calves backward. The exoskeleton system coordinates leg movements and activates the motor quickly to support the user. Intelligent algorithms adapt to the user's movement patterns, and the AI system recognizes the type of activity and automatically adjusts to it. The Z1 exoskeleton allows users to walk on average 25 km more during hikes. It has a built-in battery with 5 hours of operation and an energy recovery system that recharges the batteries during descents. The price of various modifications of the exoskeleton ranges from 699 to 1398 dollars, depending on the configuration. The company Dnsys was founded four years ago by engineers with experience in companies that produced consumer gadgets and entertainment technologies. The Z1 model was created after the success of the previous version of the exoskeleton X1, to meet user requests regarding knee support.
