We make the most affordable and reliable head impact sensors on the market.

Play Safer

Whether you're in the game or at practice, knowing when you may have a concussion is critical. The NITRON head impact sensor helps coaches and players know when they have been hit too hard and need to get out of play for proper medical attention.

Work Safer

The CABEZON head impact sensor is the first head impact sensor made specifically for the construction and labor industry. The job site is full of hazards that can lead to a worker getting a potential concussion, and its about time we take them seriously.

Serve Safer

Our service men and women need to stay as safe as possible on deployment. Our HERO head impact sensor was built to withstand the extreme environments and exposures our military faces each day. 

If it's RED, check your head. ™


What makes our head impact sensors so unique, is Tozuda's patented technology. Our mechanical acceleration technology, allows us to detect linear and rotational forces, without the use of electronics in our sensor. When a significant impact occurs, a dye gets released into our sensor body signifying that a dangerous impact has occurred. 

If activated, the sensor's red color indicates that the user should get assessed for a potential head injury, follow proper concussion protocols, and not return to the field or job until properly cleared by a medical professional.
