Ever since the late 18th century, scientists and inventors have been devising ways to enhance human telecommunication from the telegraph, the telephone, the mobile phone and now the Internet. In more recent years, there has been a hype around multidimensional media. Demand for this type of next-generation media has prompted researchers to investigate ways to add other senses, such as smell, touch and taste, to the traditional sound and sight senses. Scientists have already found ways to extract information about the human body from breath. The breathalyzer, which estimates blood-alcohol levels, was invented in the 1950s. More recently, clinicians have been using breath samples collected from patients to detect viruses, like human influenza, or even to diagnose cancers, like breast and lung tumors. Almost 1,000 volatile organic compounds have so far been identified in healthy human breath, which vary depending on health, age, diet, sex, body fat, height and lifestyle. In this project, we construct a communication system using inhaled and exhaled breath, where the information is carried in molecules. Constructing such a breath communication system will open the door to a new generation of wireless body networks, he explains. These are the communications systems used by medical practitioners, for example, to wirelessly monitor health using wearable and implanted sensors that can communicate information to a remote device.
