The burgeoning market for intelligent clothing has led to a range of wearables that monitor your health. Pictured, a t-shirt and bra by SmartLife.
SmartLife's t-shirts and bras lets wearers monitor heart rate and breathing rate via a smart device.
Conductive yarns -- most commonly made with silver -- are woven into fabrics to act as sensors that detect electrical signals, acting as electrocardiograms (ECGs). The data is transmitted wirelessly to a detection device, such as a smartphone. Pictured, the silver-coated X-STATIC fibers used by CircuiteX clothing as seen through an electron microscope.
Adidas incorporates smart technology in its miCoach shirts to measure heart rate.
These socks, by Danish company Ohmatex, monitor edema. This is fluid retention commonly found in the feet and legs and is monitored by electronically measuring the circumference of the wearer's leg. The presence of fluid can be an early-warning sign of heart failure or pre-eclampsia.
The Mbody EMG (electro-myography) Shorts -- by Myontec -- measure muscle activity in top -evel athletes. The shorts combine with a transmitter unit and a tablet app to give coaches the opportunity to fine-tune an athlete's performance.
UK company SmartLife weaves its conductive yarns into the tape, pictured, which is then sewn into clothing in relevant places to act as a detector.
Ohmatex is working with the European Space Agency (ESA) to develop smart trousers to be worn by astronauts on the International Space Station. The trousers will monitor muscle activity and wasting whilst in zero gravity.
Wearable technology has also been developed for use by firefighters to prevent heat them overheating. Three signals are collected to monitor the temperature outside of a fire suit and heat levels close to the skin, with alarms signaling when to leave. Pictured, the shoulder sensor placed on a firefighter suit, designed in consultation with Ohmatex.
