British military developed a wearable antenna waterproof polyamide yarn
Publisher: Published:2013/12/9
According to the British Engineering Network November 29, 2013 report , researchers Loughborough and Nottingham Trent University, spent three years to develop a garment can be embroidered on a prototype antenna. Alleged that the antenna is completely flexible , lightweight, waterproof. Real-time applications have been identified to be used for military and emergency services. The device can be used as bulky, heavy and not easily broken monopole viable alternative .
Professor Dias , leader of advanced textile Nottingham Trent University research team , explained that the modifications to the embroidery machinery for wire used in the manufacture of conductive antenna adjustment is necessary , you can speed up the process to promote large-scale production .
A conductive wire is covered with polyamide yarn nanosilver coating. Professor Dias explained that a key challenge is to minimize the yarn breakage at high speed friction .
Professor Diaz declined to modify the details of embroidery machinery , he said , to change the machine guides and tensioners different systems can be generated under normal production speeds.
"The key area that we have to consider is the size of the antenna , they must be very precise ," he said , "We have to improve our way of embroidery , so that we get the sense of the consistency of size , and the antenna is clean ( do not wear the fibers ) . "
The antenna has been successfully tested by washing at different temperatures , the spin cycle and wear tests have been conducted .
"We have really done their best to destroy the fabric, " said Professor Diaz said.
Further testing antenna functions , such as working in the megahertz frequency , microwave anechoic measurement chamber in the United Kingdom Loughborough University conducted .
The team includes industrial partners , access to innovative electronics manufacturing research center from the EPSRC 's (IeMRC) 465249 pounds of funding , have the ability to make antennas . |
