3rd-gen Active Textile Wearable Robot · Lower Back

Bionic Suit Waist

Lower back assist textile wearable robot

A suit that helps with work involving repeated bending and lifting. Because the fabric itself is an actuator that contracts, it is worn over everyday clothing without a rigid frame.

40%+

reduction in lower-back muscle activity*

Lower-back assist evaluation — healthy adult workers, repetitive lifting

No motor or gearbox — Fabric Muscle contracts directly, so there is no drive noise, and no frame or hinge constrains your movement

* Details such as the tested model, load and measurement method are provided in adoption consultation.
