FLUID BRAIN SCIENCE

Fluid is based on extensive scientific research and engineered to enhance your helmet’s ability to protect your brain by mimicking Cerebral Spinal Fluid (CSF) - your brain’s natural protection.  

 
 

Fluid acts as a second layer to CSF by independently and simultaneously managing the linear and rotational forces that scientific research has shown to cause concussions. 

 
 
 
 

FLUID = TOTAL BRAIN PROTECTION

Fluid incorporates a matrix of pods oriented around the head and attached to the helmet interior. Each Pod comprises a flexible membrane filled with a compressible foam disk saturated with a low shear fluid.

At the moment of impact, the foam compresses to provide added low linear impact protection. Simultaneously, low shear fluid is dispersed throughout the pod creating a slip plane that permits motion of the helmet relative to the head to provide rotational force protection.

FLUID INSIDE™ HELMET INTEGRATION

 
Each Fluid Inside™ integration is composed of a matrix of Pods arranged inside the helmet and optimally tuned to meet the needs of each sport-specific helmet application.

ROTATIONAL AND LINEAR IMPACTS EXPLAINED

 

Most helmets are designed to protect against skull fractures and intracranial hemorrhaging from impacts associated with high linear forces. 

Head and brain injuries such as concussions and subdural hematomas are the result of simultaneous rotational and linear accelerations acting on brain soft tissue.

 Impact management materials currently used in helmets manage either rotational or linear energy (not both) and exceed the shear force properties of Jell-O like brain tissue. 

 

High Energy Linear Absorption

Modern helmets are conventionally designed to provide protection from high linear forces and have successfully mitigated injuries associated with these forces such as skull fractures and intracranial hemorrhaging.

Low Energy Linear Absorption

Because helmets are designed to provide high linear force absorption, the challenge is to protect across the full range of linear forces - from ‘soft hits’ to ‘hard hits’.

Rotational Energy Absorption

Rotational "spinning" forces on the brain soft tissue are strongly implicated in concussive brain injuries, and therefore must be addressed in order to design a truly safer helmet.

FLUID BRAIN SCIENCE TECHNOLOGY

 
In order to mitigate brain injuries, all types of rotational and linear acceleration forces need to be managed independently and simultaneously.  Other important variables to assess include the shape and duration of the acceleration curves, as well as stresses and strains on the brain tissue. 
 

Rotation Dominant

   Oblique impacts where the head and brain decelerate from rotating (spinning) more slowly and can lead to greater soft tissue damage.

Linear Dominant

Rotation:  Low shear Fluid allows the helmet to rotate relative to the head and improve rotational energy absorption.    Linear:  Fluid displacement & foam compression improves high/low linear energy absorption.

FLUID IMPACT PERFORMANCE

 

The standardized testing of Fluid Inside™ applied to ski and bike helmets has shown to significantly reduce the impact severity of rotational and linear impacts by up to 39% and 22% respectively when compared to conventional ski and bike helmets.
