Smart textile• Smart textiles means intelligent textiles.• During the last decade, textiles have entered a new era,

the one of smart textiles.• It can sense and react to environmental condition or

stimuli.• It can also sense and respond in a predetermined way.

Components• There are three

components in smart textile material– Sensor

• Sensors provide a nerve system to detect signals.

– Actuator• Actuators act upon the

signals.– Controlling Units

• Controlling Units produce an appropriate output.

Classification• There are three categories

depending on functional activity:• Passive smart textile

– Using sensor only.– Only sense the environment change.

• Active smart textile – Using sensor and actuator.– Sense and react with environmental

changing.• Very or ultra smart textile

– Sensor, actuator and controlling unit present in textile.

– Can sense, react and adapt themselves to environment.

End Use• Smart textile used for the

following broad categories:– Comfort wear– Heat protection– Medical application– Military application– Computing textile– Fashion– Aviation– Space research

Methods of making smart textile• Components of smart textile

may be acting from fiber optics, phase change material, shape memory material etc.

• Those components from an integrated part of textile structure and can be incorporated into the substrate at any of the following levels.– Fiber spinning level– Yarn / Fabric formation level– Finishing level

Sensor for recording• Life shirt which are weaved

by special technique with optical fiber.• This optical fiber transmit

human physiological parameter.• Also intelligent shirt

monitors presence of poisonous gases in the air and protect human body from it.

Sensor for recording• In construction, sensor laid

in composite structures can be used to:– Monitor strain and

temperature throughout a composite structure

– Detection of crack in composite structure

– Monitor concrete structure.

What Lies Ahead?• The range and variety of high performance textiles that have been

developed to meet present and future requirements are now considerable.• They should include tera and nano scale magnitudes, complexity,

cognition and holism.• Fibers are relentlessly replacing traditional materials in many more

applications. From super-absorbent diapers, to artificial organs, to construction materials for moon-based space stations.

• Biological tissues and organs, like ears and noses, are grown from textile scaffolds made from bio-degradable fibers.

• Integrated with nano-materials, textiles are imparted with very high energy absorption capacity and other functions such as stain proofing, abrasion resistance, light emission, etc.

• In future Smart textile have artificial intelligence brain.
