HELK

HELK is a 0.7-kilogram textile lumbar-support exoskeleton for healthcare and care-sector workers who move or transfer patients. Variable-deformation elastomers act as artificial muscles, supporting movements that load the lower back while preserving a wearable, non-powered form.

HELK provides adjustable support equivalent to 7–15 kilograms and 30 newton-metres of additional force. Its stated performance figures include a 15% reduction in metabolic consumption and up to a 30% reduction in lumbar effort; the lumbar-effort figure is linked to a 2021 Journal of Biomechanics study. HELK is an occupational injury-prevention device, distinct from Gogoa's powered gait-rehabilitation systems.
