Jolt Sensor gives feedback on head impacts

It’s every athlete’s nightmare: a head injury that cuts short your game and even possibly your career. Thankfully this new sensor gives feedback on knocks so you know how serious they are.
It’s called the Jolt Sensor, and it’s a small clip that attaches to any piece of head-worn athletic equipment, such as a helmet, headband, or goggles. When the athlete’s head accelerates in a way that could be dangerous, the sensor vibrates to let them know. It also connects to parents’ and coaches’ smartphones, so they stay up to speed on what kind of impact the player has incurred.
It connects to phones using Bluetooth Low Energy, which has a range of over 100 yards.
When it detects a dangerous impact, the parent or coach receives a notification that the player should be evaluated immediately. The app has its own cognitive test and concussion symptom checklist that’s easy to follow. If the player shows any signs of concussion they should be taken off the field and evaluated by a doctor.
It should mean nobody tries to carry on playing with a potentially dangerous head injury.
All the data is stored in the cloud, for easy access by a doctor. The device is encased in silicon rubber, so won’t hurt your head if you fall on it, and is fully waterproof and dustproof.
The project has only just launched on Kickstarter, and has already raised $12,150 of its $60,000 target. You can back it for a minimum pledge of $1.
