Versatile by design, Tozuda sensors are well suited for all helmeted activities, easily fitting onto any piece of headgear and into any routine. For bikers and cyclists, our sensors provide extra information and peace of mind, so that you can stay focused on the road ahead.


Objectively indicating concussion probability, Tozuda sensors are ideal for use in contact sports, as their simple attachment process and clear activation make prioritizing safety easy and affordable for athletes, coaches, and teams alike.


Our sensors are made with impact-resistant polycarbonate and can withstand regular helmet use, minor impacts, extreme temperatures, and reliably indicate in any setting when a potentially concussive impact has occurred.
