Knee exoskeleton announced that increases leg strength by 50% and reduces knee strain by 200%

Hong Kong-based Dnsys has unveiled the Z1 knee exoskeleton, which increases leg muscle strength by 50% and reduces knee strain by up to 200%. This is reported by New Atlas.

The device has a hinged design weighing 680g per leg and is equipped with a 450W electric motor. The model was created by a team of engineers with experience in Segway, DJI and Xiaomi as a continuation of the previous X1 device, which focused on the hip joints. The new modification was developed in response to requests from users who need additional knee support.

The device is equipped with a dual-core processor with a frequency of 240 MHz and a number of sensors, including torque, position and force sensors. The system responds to the movement of the leg within 0.01 seconds, adapting to the user's gait using AI algorithms. The exoskeleton automatically switches modes according to the type of activity – walking, running, cycling, jumping or squatting.

The model has an IP54 protection class and works autonomously for up to five hours. Kinetic energy recovery is provided when moving downhill. In hiking, the Z1 increases the average distance a person can cover by 25 km. When climbing or jumping, the exoskeleton creates a feeling of weight loss of 20 kg, and during descent it reduces pressure on the knees by up to 150 kg.

Dnsys offers three variants of the Z1: the basic Single Joint, the standard Dual Joint made of aluminum and carbon, and the premium Dual Joint Pro made of titanium. The pre-order price for the Single Joint version is $699, for the Dual Joint – $899, and for the Dual Joint Pro – $1398. The retail prices for the new product will be $1099, $1499, and $2298, respectively.

The manufacturer is currently running a Kickstarter campaign to launch mass production.
