Impact Indicators are devices that alert a participant or bystander when someone has been hit too hard during their activity. Tozuda's Impact Indicator can attach to any type of helmet with only double-sided tape.
Impact Indicators are NOT designed to detect or prevent concussions. Impact Indicators are designed to detect or react to linear and rotational accelerations that the head may undergo. When a dangerous threshold has been reached, users and/or bystanders are alerted through the indication of the Impact Indicator when it turns colors from clear to red.
If there is any indication that a head injury has occurred, seek medical attention as soon as possible. Only a licensed medical professional can legally and properly diagnose a concussion.
