Developing Next-Generation Impact and Real-Time Head and Brain Motion Sensors

Head kinematics following impacts induce complex motion leading to brain injury. New kinematic measurement methods and advanced sensing systems can quantify motion that causes injury.

Understanding the link between head motion and injury when rotation is present requires measurement of the acceleration at all points in the head, not just resultant acceleration at the center of mass.

Through the application of a revolutionary algorithm, inexpensive accelerometers can predict acceleration at every point on a rigid body.

This breakthrough in measurement provides a tool to improve helmet testing, injury detection and will allow for the development of protective devices that are activated in response to an impact.
