Dnsys Z1
Hong Kong-based startup Dnsys has unveiled the Z1 knee exoskeleton, which radically changes the concept of human mobility. The device strengthens the leg muscles by 50% and reduces the load on the knee joints by three times. Each of the two exoskeleton modules weighs only 680 grams and attaches to the legs in 15 seconds. Built-in 450-watt electric motors support the hip when moving forward, assist the calf muscles when pushing off and reduce the subjective load when lifting by 20 kilograms.
The system responds to the start of movement in 0.01 seconds thanks to a set of sensors that track position, force and torque. A dual-core processor (240 MHz per module) analyzes the user's biomechanics, gradually adjusting the work to his individual manner of movement. The device automatically recognizes walking and running, cycling, jumping, squatting and various static positions.

When tested in field conditions, the Z1 increased the walking distance by 25 kilometers and reduced the impact load on the knees to 150 kilograms. The device is well protected from moisture and splashes and is capable of operating independently for 5 hours. The startup offers three execution options — "Single Joint", "Dual Joint" and "Dual Joint Pro", which are offered to customers at prices of 699, 899 and 1398 dollars. The developers emphasize that the Z1 is an evolution of their previous X1 model, which focused on hip support. The new solution addresses the user's request for knee protection during active loads. The project is currently raising funds on Kickstarter, offering early investors a substantial discount.
