Assistive
Devices
This lower back exoskeleton uses the resistance of elastic band to support the upper torso during forward bending tasks.

We focus on

Nonlinear Support Force

The energy storage system supports the upper torso when bending forward while allowing unrestricted movement when bending to the ground.

Shape Conformity

Human motion is rarely purely rotational; the device's flexibility allows for a combination of rotational and translational movements that conform to the body during operation.

Everyday Usage

Exoskeletons should be comfortable, easy to wear and remove, and intuitive to control to promote everyday use.
