Company Cambridge Consultants will demonstrate at CES 2011 the concept of i-dration, a bottle of water, aimed at an audience of fitness clubs.
Sensors on the bottle exchange data with an application on a smartphone owner. Bottle measures the ambient temperature, the amount of absorbed liquid, and also how often you put into it. Telephone, meanwhile, will be using its accelerometer to determine how hard you work on yourself, by comparing these data with the cardiac rhythm, which is measured thoracic belt.
After the necessary calculations, the application will determine whether you are experiencing a lack of fluid, and if so, the bottle will turn blue light.
Not sure what is so bother to decide whether or not to drink the water, but fans of fitness and healthy lifestyle in general, certainly have an opinion on this matter
