A new technology that will allow you to use your body as a network transmitter is being developed in Japan.
Called RedTacton, the Human Area Networking technology uses the minute electric field emitted on the surface of the human body to transmit data from one device to another.
According to the makers using the system means touching, gripping, sitting, walking, stepping and other human movements can be the triggers for unlocking or locking, starting or stopping equipment, or obtaining data.
The system works by creating a transmission path at the moment a part of the human body comes in contact with a RedTacton transceiver. Physically separating ends the contact and thus ends communication.
Using RedTacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user's natural, physical movements.
Communication is possible using any body surfaces, such as the hands, fingers, arms, feet, face, legs or torso. RedTacton even works through shoes and clothing as well.
One suggestion for the technology is for the system to be embedded into medicine bottles that would then transmit information on the medicines' attributes. If the user touches the wrong medicine, an alarm will trigger on the terminal he or she is carrying. The alarm sounds only if the user actually touches the medicine bottle, reducing false alarms common with passive wireless ID tags, which can trigger simply by proximity.
NTT, who is developing the technology plans to Commercialise the technology once testing has been completed, although currently there is no firm date as to when this might be.
