Japet W +: exoskeleton with a zero-power lens

Japet is known for its exoskeleton models, including the Japet W+—a motorized lumbar exoskeleton that effectively helps relieve chronic or acute back pain, both at work and in everyday life.Designed for professionals who perform repetitive physical tasks such as lifting heavy loads or maintaining uncomfortable postures, as well as for people suffering from back pain, this device definitely deserves more attention.

Features of the Japet W +

Our device of the day, the Japet W+, is very lightweight, weighing only 2 kg. With its lightweight and discreet belt-shaped textile structure, available in two sizes (T1 and T2), it is perfectly designed to adapt to different body types and ensure comfort while performing your tasks. On the technical side, the Japet W+ features four micro-motor actuators that act as shock absorbers for the spine and allow the lumbar support to be adjusted across four intuitive levels. It reduces lumbar pressure by 40%. Thanks to the built-in battery, you’ll enjoy up to 7 hours of continuous use, depending on the selected intensity level.

If you're worried about wasting time on threading, rest assured that installation takes only 30 seconds to one minute, with a single clamp to hold it in place and simple adjustments to help you out. The fabric cover is removable and the machines are dishwasher-safe, making them ideal if you need to share them among your team.

In accordance with ISO 13485 and the CE IIa medical device classification, sensors are incorporated that adjust the support based on detected movements, thereby maintaining mobility and muscle engagement. However, specific medical contraindications require prior consultation. It is particularly suitable for demanding environments, such as manufacturing, logistics, agriculture, or healthcare, where it can reduce the time spent in high-risk positions by up to 85%.

Japet W+ Study and Opinion

Approved clinical trials—including three completed and two ongoing studies, as well as a dedicated thesis—confirm the effectiveness of Japet W+, with a 40% reduction in lumbar pressure, a significant reduction in pain, and minimized impact on the spine, involving fourteen companies and four partner centers. Users highlight its lightness, ease of use with quick, self-installation, comfort while in motion, and customization through adjustable support levels. Consequently, it reduces work-related musculoskeletal disorders and supports business productivity thanks to its non-invasive and well-accepted design. Evidence points to an immediate impact on back pain, even during dynamic tasks, and a reduction in physical limitations without compromising mobility. Among the identified limitations are the need for monitoring over very long periods, precise initial fitting, and contraindications for certain extreme body types or skin conditions. However, it remains generally regarded as one of the lightest and most efficient powered exoskeletons available. Any questions? Contact us.
