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

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.
