Impact Indicators are devices that detect a wide range of impacts, and Tozuda’s Impact Indicators do so completely without electronics. Tozuda’s Impact Indicators are able to be set at different thresholds; whether for head injury awareness, helmet damage indication, or another custom setpoint as needed. We have the ability to tailor activations between 10 and 700 G’s (G Force, a measure of acceleration.)

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.

While there are other impact indicators on the market, Tozuda beats them all with its patented mechanical technology that allows for no electronics and an instantaneous indication, while being user-friendly and affordable.

Once the indicator activates, it is no longer usable, it has to be replaced.

Before activation, the spring will be in a straight alignment, sitting perfectly horizontally across the middle chamber. The indicator is activated if there is any displacement within the ball-and-spring system.

When activated the middle chamber will begin to fill with red color.
