Title: Smart Materials


1
Smart Materials
  • Smart textiles are materials and structures that
    sense and react to environmental conditions or
    stimuli, such as those from mechanical, thermal,
    chemical, electrical, magnetic or other sources.
  • Smart textiles are no longer a science-fiction
    fantasy. For example, there are in the market
    self-cleaning carpets, memory-shaped and
    environment-responsive textiles, and
    anti-insomniac micro-fibers.

2
What do they do?
  • Passive smart materials, which can only sense the
    environmental condition or stimuli,
  • Active smart materials, which sense and react to
    the condition or stimuli,
  • Very smart materials, which can sense, react and
    adapt themselves accordingly, and
  • Intelligent materials, which are those capable of
    responding or activated to perform a function in
    a manual or pre-programmed manner

This is an ongoing research project in the field
of Smart Textiles. In the glove all the
technique for communication is integrated in the
textile product. The glove is intended to be
used under extreme climate conditions, for
example where the temperature is very low and you
are exposed to snow and wind. You can use your
mobile phone without taking off your glove and
there will be more different possibilities for
communication in this and other coming products.

To be included in the next-to-skin category for
Polartec, a fabric must actively pull moisture
away from your body (wick), dry quickly, breathe
and be comfortable on your skin. No matter what
season, weather condition or activity you face,
this is the most critical layer for comfort and
performance. We include two fabric series in the
next-to-skin
6
Polartec Power Dry fabrics are designed to keep
your skin dry when you sweat. All fabrics in this
series feature a patented bi-component knit
construction that uses different yarns on either
side of the fabric. This creates two different
surfaces one that is optimized to move moisture
away from the skin, the other to dry quickly.

I WONDER WHAT MAKES KEVLAR SO STRONG ??
Under water, Kevlar is 20 times stronger than
steel. These Kevlar cables are supporting a
sonar facility that the U.S. Navy uses to find
out how much noise submarines make.
Everything you need to know about Kevlar can be
found on this site www.lbl.gov/MicroWorlds/Kevlar/
Police wear bulletproof vests made of Kevlar.
Windsurfing sails that can withstand the force of
60 mph winds and don't rip easily are made of
Kevlar.

Medical Smart Materials
The medical profession is now using many smart
materials for a variety of medical conditions.
The latest is a dressing that has incorporated
sensors for monitoring patients.The "intelligent
textiles" contain embedded sensors designed to
monitor body fluids such as blood and sweat. The
aim is to use the clothes to check on groups such
as recovering hospital patients, people with
chronic illnesses and injured athletes.
A prototype multi-sensor test patch is already
near completion.
