At the Wearable Technology Show, there were many vendors demonstrating clothing with built-in sensors and lights – I think there was even one with a Raspberry Pi tucked away in the lining. All of them have the problem of how to get power from a battery pack to the electronics and one solution is to use a conducting thread or yarn. Statex have a silver-based yarn which can be woven or embroidered into a cloth to make a circuit. The silver and polyamide mix gives a balance of lightweight and elasticity while still conducting electricity. I discuss the practicalities of silver threads with Robert from Statex. Statex were demonstrating the properties of the silver yarn with a small keyboard that was embroidered into a cloth along with a small circuitboard to produce the tones and flash some lights. It’s not a baby grand piano, but it’s lots of fun and shows off the potential. They were embroidering some of them at a nearby stand and I’m sorry I didn’t snaffle one! Statex is a world-wide leader in the silver-coated fabrics industry. The company has successful developed silver-based yarns, textiles, bandages and carpets which provide a range of benefits from electrical conductivity and RF shielding to anti-bacterial and fungicidal properties.
