The T-shirts printed with "E="mc2" will no longer be patented by the scientific and technological elites. By entangling the polymer fibers, researchers will weave transistors and other simple logic circuits into the warp and weft of textiles. The researchers said that this fabric with computing power may be able to track the patient's health status or provide assistance to soldiers in identifying chemical weapons."
This calculated fiber has been available for more than 10 years. For example, in 1996, researchers at the Georgia Institute of Technology in Atlanta, USA, developed a shirt full of sensors that could monitor the patient's heartbeat, body temperature, and respiration in real time. Other researchers have added microsilicon chips to the fabrics they make, giving them initial computing power. However, these devices must be sewn into or attached to the fabric by some methods, thus adding extra cost and being prone to failure during use.
Today, the chemist Olle Ingans of Linkping University in Sweden and his colleagues decided to try to convert the circuit into the fabric's own fibers. Researchers initially coated a nylon cord surface with a conductive polymer complex (PEDOT/PSS) and then applied a small amount of conductive polymer electrolyte at the intersection of the two nylon cords. After drying and hardening it becomes an electrical conductor between the two nylon ropes. Ultimately this intersecting fiber acts as a transistor - when a voltage is applied to one of the nylon ropes, the current will flow between the intersecting networks.
Researchers recently reported the results of this research in the online edition of Nature-Materials. Researchers even woven this nylon cord into traditional textiles, creating a new connection model - two circuits that follow digital logic, namely non-gate inverters and multiplexors. Whether this fiber can withstand the test of the washing machine is not yet known, but Ingans said that the fiber and the transistor are waterproof.
According to Barry DeCristofano, a chemical engineer and electronic textiles specialist at the Natick Military Research and Development and Engineering Center in Massachusetts, USA, this new method offers new possibilities for integrating different types of lines into textiles. DeCristofano said: "These conductive fibers can be woven into clothing to enable people to connect with the world in many different ways."
