The NEXUS A9 is a highly engineered custom mouth guard utilising micro motion sensors to detect head impacts to a high degree of accuracy.

Our team of engineers & neuroscientists have worked tirelessly to deliver a data driven solution to impact detection. It is the culmination of a 2-year research and development phase.

Nexus A9

Only valid tool to measure head impacts

Not compromising comfort, the Nexus A9 is a functional, valid & reliable solution to accurately measuring the magnitude, location & direction of head impacts

Advanced Impact Recognition System

See the invisible

Purely relying on our vision to detect head impacts, in many instances over large distances on the sporting field, has proved to be a flawed approach. Our Advanced Impact Recognition System (AIRS) is a point of care alert system to medical professionals and caregivers in the form of a user-friendly software application. Our AIRS is the interplay between hardware, firmware & software to deliver complex information in the most efficient way possible.
AIRS allows for Rapid Response to potentially traumatic head injury through efficiently applying our proprietary algorithms to the raw data and communicating simple & insightful data to the end user.


Insightful Data

Our Impactrak function is a longitudinal overview of an athlete’s impact history, utilising predictive analysis to compare and recognise possible head injury based on previous cognitive and clinical outcomes to historical impacts. Utilising big data, we are able to analyze often overlooked impacts and begin to make meaning of not only the single high-level impact but also the accumulation of smaller impacts over a given time period.

Delivery of detailed reporting systems can alert the medical professional to both acute and chronic behavioral changes experienced from past events of similar magnitude, direction & location.

Finite Brain Modeling

Understand injury risk

By using highly accurate computational models of brain injury, we are able to map out the brain tissue response to head impact loading through the data derived from the Nexus A9.

In utlising the sensor information, maximal strain and strain rate can be identified against profiled impacts and give deeper understanding of potential pathologies. This allows precision medicine to take place where more specific rehabilitation can be used as an intervention in the overall management of the concussion.
