Textiles are everywhere – from the clothing we wear, bandages we use
to heal, and structures that shelter us for protection, each fabric is
carefully selected for its unique construction and properties.
But what if the clothing you wore could monitor your heart rate and
transmit medical alerts to your doctor? Or if the bandages you affix to
your skin didn’t just cover a wound but dispensed healing medication.
That’s where smart textiles come in.
Smart textiles are materials and structures that detect and respond to external stimuli, such as
mechanical, thermal, chemical, electrical, magnetic, or other sources.

Fabrication Methods of Smart Textiles
Several methods are used to integrate the different parts to get a
smart textile structure. As a result, the integrating techniques of
these starting materials differ.
•Conductive or Responsive Compounds
•Conductive or Responsive Yarn or Filament
Fiber
•Conductive or Responsive Fabric/Sheet

These fibers include conductive yarns and polymers,
shape memory polymers, encapsulated phase change
materials, fiber optics, and other small electronics.
Depending on their use, smart fabrics are created by fusing
together fibers and technology.
They may also use external additions, such as:
These materials interact with one another along with an
external stimuli — such as temperature, light or pressure —
creating a transfer of energy.
•Sensors
•Chemical treatments
•Thermochromic dyes

Once activated, the functional fabric responds depending upon the textile’s function.

Smart textiles is a sector that has been developed with new
technologies, new fibers, and textile materials.
The production of smart or intelligent textiles cooperate with
other branches of science like nanotechnology, materials
science, electronics, and computer engineering, etc.
Good morning everyone , today i’d like to present my project about smart textiles wearble microsystems presented by me

First i will start with introduction

Smart textiles are materials and structures that detect and respond to external stimuli, such as mechanical, thermal, chemical, electrical, magnetic, or other sources.
Understanding the evolution of smart textiles through time can assist in identifying future growth patterns and opportunities
Smart textiles can be classified in three categories according to its functional activity.
* Passive smart textiles can only sense the environment, as they are just sensors
* Active smart textiles can sense the stimuli from the environment and also react to them; besides the sensor function, they also have an actuator function.
* Ultra smart textiles are materials that sense, react, monitor, and adopt themselves according to the stimuli or environmental conditions, such as thermal, mechanical, chemical, magnetic, or other sources
It all sounds nice and exciting – but the question is how do they work in particular !
where are the advantages in use?
The four basic elements of wearable smart electronic textiles are conductivity, sensors, wireless communication module, and power supply. Depending on the nature of these components, the degree to which they can be integrated into the textile material varies.
an external stimulation — such as temperature and light or pressure
Sensing : the sensor recieve information from the environment , and transform it to electric signals
The processor analyse and evaluate the signals
The actuator act upon the detected and evaluated signal either direct or from a central contrôl unit and hand over the instructions to enviroment
In this way, smart textile works out successfully.
Besides sensors and actuators there is a group of materials that conducts electricity, these are the conductors
They can be categorized:
conductive inks,
carbon-based conductive polymers
, intrinsically conductive polymers
and conductive polymer composites
They are widely used in smart textile applications such as sensors, communication, heating textiles and electrostatic discharge clothing.
The second material is fiber optics
These Materials respond to external stimuli, also known as smart materials.
These objects can change :
Color using chromic materials
shape fabric usig shape memory materials
or behavior when exposed to heat, mechanical stress, chemicals, light, magnetic field, etc.
Smart materials are incorporated into the textile structure by different technologies; embroidering [90], knitting [91], weaving [92], spinning [93], braiding [94], coating [66], printing [84], plating [95] and chemicals that provide specific features such as controlled hydrophobic behavior [4].
At its core, technical textile manufacturing is a vast landscape of advanced yarn systems combined with textile formation techniques. The completed construction can be further transformed through lamination, coatings and composite methods.
Depending on their use, smart fabrics are created by fusing together fibers and technology. These fibers include conductive yarns and polymers, shape memory polymers, encapsulated phase change materials, fiber optics, and other small electronics. They may also use external additions, such as:
Sensors
Chemical treatments
Thermochromic dyes
These materials interact with one another along with an external stimuli — such as temperature, light or pressure — creating a transfer of energy.
Once activated, the functional fabric responds depending upon the textile’s function.
textiles offer unique opportunities to integrate electrical functionalities at various levels—from fibers, yarns, to the finished product
smart fabrics are created by fusing together fibers and technology. These fibers include conductive yarns and polymers, combined with textile formation techniques.
Conductive filament fibers, yarns, and metallic wires can be integrated into/onto a textile structure by weaving, knitting, embroidery, and braiding techniques.
The benefits of Smart textiles are just infinite and some of them are just around the corner waiting to be discovered.
