Protect your head from injury with the Tozuda Head Impact Sensor. Incredibly simple to use, this sensor offers a reliable solution for concussion awareness. Tozuda sensors are able to detect forces in all directions. Likewise, they work within milliseconds of impact. Enduring normal or minor contact, the sensors only alert you to a potentially concussive hit. Tozuda sensors turn red once a significant impact has occurred, letting you know that you should be evaluated for a head injury. In addition, the sensors offer a simple attachment process and clear activation. Tozuda’s patented technology also allows the sensors to function without using electronics, making it affordable. Simply attach Tozuda to your favorite helmet for biking, motorcycle, football, hockey, and more to stay safe.
