Meet the U-Wake: an innovative wearable device that reads your brainwaves to determine when you are too tired and vibrate to keep you alert. It pairs with your smartphone and can send alerts to your family members when you are too tired. The device is lightweight and made of food grade materials. It sends data to your smartphone via Bluetooth.
The U-Wake is expected to have a SDK for developers. You can find the device on Kickstarter.
