U.S. researchers have developed radio antennas that can be sewn directly intoclothing.
The team of Ohio State University has created a prototype using a plastic film and metallic thread.
The scientists reported in the IEEE Journal that the system range is four timesgreater than that of a conventional antenna carried in the body.
The technology could be applied in various fields, but is primarily designed formilitary use.
"Our goal is to improve the reliability of communications and mobility of the soldiers," said Chi-Chih Chen, one of the researchers.
"But you could use the same technology for police, firefighters, astronauts or for anyone who needs a free hand for an important job."
The first prototype antenna is integrated into a plastic film, and then sewn to the fabric with the help of an ordinary sewing machine.
To ensure that the signal is strong and the antenna is multidirectional, scientists place multiple antennas in a piece of clothing: in the front, rear and on both shoulders.
They all work together - along with an integrated control computer device - to detect body movement and switch to the optimum antenna.
Currently, implementing the technology would cost about $ 200 per person, according to developers. But once it reaches mass production, we expect the price to drop.
