Wearable technology

Advances so far: Adopting electronic displays (LEDs) technologies to create colorful, novelty clothing items for example, glow-in-the-dark bridal gown, sparkling cocktail dresses, and costumes for opera singer. Further progress is expected in the form of tailor-made clothing.

* Fibers powered by tiny, rechargeable batteries that are turned on by the wearer via a hidden switch causing the fibers to give shininess when the lights are dimmed.

* Development of a flexible, battery-powered optical fiber screen that can be woven into clothing. A prototype version integrated into a jacked displaying symbols is already in the market and more sophisticated versions may support advertising slogans, safety notices, or simply a range of different geometric patterns can be switched on and off.

* Production of low-cost jackets for joggers and walkers with a pulse monitor stitched to the left cuff. Embedded sensors control conductive material on the back of the jacket to keep the wearer warm should the temperature drop, while electroluminescent wires are fixed to pockets and hems to light up in the dark as a safety feature.

The marriage of woven fabric with electronics is finding favor in the world of interior design as well inform of electro-textile wall panels. The panel exploits reflective coloring. The fabric contains interwoven stainless steel yarns, painted with thermo-chromic inks, which are connected to drive electronics programmed to change color in response to heat from the conducting wires. At the outset, main users are going to be medical, military, and industrial areas with compelling applications and affordability. The simulation environment is already being used to model a garment that can sense its own shape thus helping patients to learn about their exercise requirement. Creating a wearable version of a giant textile sensornet designed to detect noise.

It is envisaged that efforts should be to stay as close as possible to conventional large-scale cutting and sewing techniques when thinking about how electronic textile clothing could be made. Cutting electronic cloth clearly makes it more difficult to make good connections between different parts of the same garments and one solution to it could be the manufacturing of seamless clothing, which would avoid the cutting and stitching problem altogether. The cost of developing and manufacturing such sophisticated fabrics is likely to put them beyond the reach of the fashion industry for the time being. Connections will be main point of weakness in electronic clothing.
