Smartwear is seeing another influx of innovation. Researchers at Ohio State University have developed a technology for creating embroidered patterns using a metal thread with a thickness of 0.1 mm. By creating various patterns, you can now make, for example, a T-shirt that amplifies the signal of a mobile phone or a hat that controls the activity of the brain.
The concept of "embroidery" is hardly associated with ultra-modern technologies today, but a new generation of products called "e-textiles" refutes this statement. When creating them, sewing machines are used to sew special patterns of metal threads into the fabric based on a template designed on a computer.
Machine for embroidery schemes
Work on the creation of a new technology has been going on for several years. In the beginning, the researchers worked with silver-coated polymer filaments 0.5 mm in diameter, consisting of 600 microfilaments twisted together. Currently, the team is dealing with thinner products - 0.1 mm, consisting of only seven threads. Their structure is a copper core coated with pure silver enamel.
RFID chip in rubber
The operation of the circuit depends on the drawing. For example, a broadband antenna can be created by embedding numerous intertwined geometric shapes in a circular pattern several inches in diameter. Making it requires wires costing 30 cents and 15 minutes of work. Experiments are also underway to embed an RFID chip into rubber, which could find applications in car tires.
