Modems for the human body - already in stores

    The Japanese company NTT began selling devices called Firmo , which can transmit traffic using the human body as a conductor. Thus, people can upload information to electronic devices simply by touching them.

    The main component is a small transmitter card that can be worn, for example, in a jacket pocket. It performs digital-to-analog conversion of data into an electrical signal that spreads through the user's body and breaks even through clothes or shoes. If a person touches any device equipped with a receiver, then the information is transmitted there directly. At the moment, speeds up to 230 Kb / s are provided. NTT engineers are now working on a new version that will provide broadband body communication at speeds up to 10 Mb / s.

    This development is based on RedTraction technology from the same NTT. It is assumed that in the future in this way people will be able to exchange even geneticpersonal information with a simple touch of each other. But this is in the future, and now the main field of use of such gadgets will be a variety of security applications, as well as “smart” houses and offices that can recognize the identity of any person who touches the door handle.

    NTT Firmo went on sale April 23, 2008 at a price of $ 8,000 for a set of five transmitters and one receiver. After the organization of mass production, the price can be reduced by one or two orders of magnitude.
