Tozuda manufactures the most simple and affordable head impact indicator for concussion awareness. All you have to remember is "If it's red, check your head."
Tozuda was founded in 2014 when the CEO and founder, Jessica Garcia, went looking for a head impact sensor after her concussion went undetected during a rugby match. When seeing that the options were limited by expense and ease of use, she turned to developing a new product. The Tozuda Head Impact Sensor is a mechanical accelerometer that indicates red when a person has been hit with a force that has been associated with causing a concussion.
