Professional athletes use this Smart device during the Match ?

Invention holds great promise for all sorts of new devices and materials

The invention holds great promise for all sorts of new devices and materials with the ability to regulate temperature and heat flow on demand, including the ‘smart’ fabrics.
“The switching effect of thermal conductivity would be ideal for many applications, including athletics,” says the candidates in UVA’s Department of Materials Science & Engineering and lead author of an article about the invention published recently in ‘Nature Nanotechnology’.
“This material has the potential to revolutionise activewear, unleashing the possibility of clothing that can dynamically respond to body heat and regulate temperature. For example, the biopolymer has a low thermal conductivity while dry, essentially storing body heat and keeping the athlete (and his or her muscles) warm while not active
“As soon as the wearer begins to sweat, the material could become hydrated and instantly increase its thermal conductivity, allowing this body heat to escape through the material and cool the athlete down. When the person is done training and the sweat has evaporated, the material could go back to an insulative state and keep the wearer warm again.
“And while it may sound highly specialised and only for professional athletes, it would be equally useful from an apparel company perspective,”

Garments made using technology would be a step above what is available on market today

The garments made using this technology would be a step above what is available on the market today because of the materials’ extremely wide range of technical capabilities. For example, polar fleece generally requires different weights to accommodate different combinations of temperatures and activity levels.
The new material could accommodate the whole gamut of athletic scenarios within one garment. Fleece is considered breathable, a passive state, but the biopolymer material would actively conduct heat out of the garment.
“While realising thermally and mechanically smart fabrics are one major advance of this work, the ability to provide such large and reversible modification in the thermal conductivity of a material ‘on-demand’ has potential game-changing applications,”
“The thermal conductivity of materials is typically assumed to be a static, intrinsic property of a material. What we have shown is that you can ‘switch’ the thermal conductivity of a material in a similar way that you would turn on and off a light bulb via a switch on the wall, only instead of using electricity, we can use water to create this switch. This will allow for dynamic and controllable ways to regulate the temperature and/or heat flow of materials and devices.
