What are impact sensors?

Impact sensors are devices that alert a player or coach when one has been hit too hard during game play. Most impact sensors can attach to a variety of sports equipment.


What are impact sensors designed to do?

Impact sensors are NOT designed to detect concussions. Impact sensors are designed to detect linear forces and accelerations a player is subjected to while playing on the field. When a dangerous threshold has been reached, players and/or coaches are alerted via the impact sensor.


Why is the identification of a concussion so important?

A concussion is a serious brain injury and if not taken care of properly, could lead to permanent brain damage, either physical and/or psychological. When a concussion is not diagnosed by a doctor the first time a player gets concussed, they are susceptible to further brain injury.   


What makes tozuda different from other impact sensors?

While there are other impact sensors on the market made with costly electronics, our sensors are user-friendly and use mechanical technology to sense the same information in an alternative manner. 


What are the symptoms of a concussion?

Signs of a Potential Concussion:

  • cannot remember events that happened before or after the impact

  • forgets plays/instructions, is confused about the game itself (i.e. confusion about the game, score, or opponent)

Who can diagnose a concussion?

Legally, only a doctor can diagnose a concussion.


Does the Tozuda sensor detect concussions?

No, Tozuda sensors cannot detect concussions, only a doctor can do that. Our sensors detect force at a potentially dangerous threshold and activate to alert users.


What do I do if I think my child is concussed?

If a concussion is suspected, instruct your child to stop playing and educate them on the dangers of concussions beforehand. Have the coach take your child out of play, or personally do so, as soon as possible. Do not allow them to continue game play or practice until they can be evaluated by a medical professional. Follow their instructions accordingly.


What do I do if my child is diagnosed with a concussion?

After your child is diagnosed with a concussion by a doctor, they should not be playing sports, or they risk further brain injury. Your child should not return to play until a doctor has given written medical clearance. To enhance recovery, your child should minimize screen time and refrain from using technology, listening to loud music, and limit exposure to bright lights. Make sure to contact your child's school to alert them of the issue as well as the impact their injury might have on their performance in the classroom as well.


Can I gift a sensor to someone else?

Our sensors are optimal for any activity, sport, or job-site; the opportunities for use are endless! But if you'd prefer a sensor go to a team or player in need, we can help you do that too. We offer sponsorship opportunities to help outfit local youth sports teams with sensors, or you can gift sensors to a team of your choosing. For information on sponsorship opportunities get in touch with us at if you have any questions or special requests.
