“Do you smoke?” will be a question of the past, this new sensor will be able to detect weather you are smoking, coughing, chewing and more. So no more lying to your doctor. To some this may be crossing the line of privacy but to others its a breakthrough that will really help with their diet, or to even quit smoking. It may even be able to communicate to you to your phone through bluetooth. Keeping track of your daily calories couldn’t get any easier.
