Global semiconductors specialist ST Microelectronics has announced that the newly-launched Brain Sentry Impact Sensor uses ST’s MEMS accelerometer to collect data from collisions on the sports field. The new Brain Sentry Impact Sensor is a lightweight helmet-mounted impact-monitoring device designed to monitor head impacts that may cause concussions or other brain injuries.
ST’s low-power, high-g tri-axial accelerometer integrated in the Brain Sentry Impact Sensor accurately measures acceleration in all directions produced by collisions. The data collected and reported by the Brain Sentry Impact Sensor allows coaches, trainers and doctors to monitor players after every hit, with the goal of identifying players who should be further evaluated, and reducing the number of sports-related brain injuries.
Greg Merril, co-founder and CEO of Brain Sentry explains that the risk of concussion increases as the acceleration experienced by an athlete’s head increases. A key objective of the Brain Sentry Impact Sensor is to optimise the ability to predict injury, with ST MEMS accelerometer’s high degree of accuracy critical to the achievement of that goal.
The small size of the ST MEMS accelerometer has enabled Brain Sentry to produce a light (1-oz) compact device that simply sticks to the back of any helmet. The accelerometer’s low power consumption with the sophisticated battery-life management system developed by Brain Sentry ensures the impact sensor can be used for a full year without charging. The device is also fully sealed and waterproof.
According to Benedetto Vigna, Executive Vice President and General Manager, Analogue, MEMS and Sensors Group at ST Microelectronics, the ability to quickly assess the impact of a hit or collision during a game or practice is important in order to ensure the safety of the athlete. Brain Sentry’s choice of ST’s MEMS accelerometer demonstrates the successful collaboration between the two companies to track impact and report that data quickly and accurately.
