What is MIPS?
MIPS is break through brain protection helmet technology.
The Multi Directional Impact Protection system (MIPS) is designed to add protection against the rotational motion (or kinematics) transmitted to the brain from angled impacts to the head. The rotational motion is a combination of rotational energy (angular velocity) and rotational forces from angular acceleration that both affect the brain and increases the risk for minor and severe brain injuries. MIPS’ added protection system has been proven to reduce the rotational motion when implemented in a helmet by absorbing and redirecting energies and forces otherwise transmitted to the brain.
What is Rotational Motion?
Rotational motion, in these cases, is the result of an angled impact to the head. A sudden stop will cause the brain to move or stretch. This happens mainly due to the brain’s suspension in the cerebrospinal fluid and because the brain itself has shear properties like water.
It is known that the human head is more sensitive to rotational motion than linear motion. From an engineering perspective, rotational motion is a combination of rotational energy (angular velocity) and rotational forces (angular acceleration) that both affect the brain and increase the risk for minor and severe brain injuries. The reason that the brain is more sensitive to rotational motion is that the brain is very much like water or a gel when it comes to its shear properties. The brain, like water, is also incompressible. Therefore, a linear motion will not affect the brain as much as a rotational motion.
How Does Rotational Energy Affect the Brain?
Several researchers have linked severe brain injuries like Diffuse Axonal Injury (DAI) and Subdural Hematoma (SDH) to rotational motion transmitted to the brain from angled impacts. Mild Traumatic Brain Injury (MTBI) or concussion is also believed to be caused by rotational motion.
