Smart fabric is a phenomenon that entails merging computer
components seamlessly into ordinary clothing.
manufacturers use various conductive textiles, data and
power distribution as well as sensing circuitry.
There are various techniques used to build circuits from
commercially available fabrics, yarns, fasteners and components.
Smart fabrics are fabrics that can change or react automatically
to their surroundings.
These response could be thermal, chemical, mechanical, electric,
magnetic or from other source.
Smart fabrics are being developed by scientist not only keep you
warm but also cool, dry, moisturised and free of bacteria, odour
and stains while measuring your heart rate.
These components may range from microcontrollers to sensors

Smart Fabrics in Electronics
Collapsible Impulse Radiating Antenna.
Smart Fabric heater
works on demand - heating is activated under pressure
Wireless Fabric Keyboard
• The Wireless Fabric Keyboard provides a 63-key QWERTY layout
and has a footprint of 306mm.
• The only control is a power on/off button.
• First we have to press quite hard on the slightly raised 'keys' to
get a result, which is signalled by an audible click.
• battery life -10 hours.
Wearable Electronic Textiles
Wearable electronic textiles are often controlled by soft
switches which are sewn into products using printing, coating
Switches are washable and durable.
It will eventually be incorporated into interior textiles to
control lighting, appliances, TVs and stereos.
They can be used to dial telephones, pager messages and
control music from MP3 players.
Sun Protective Clothing
clothing is clothing specifically
designed for sun protection and is
produced from a fabric rated for its
level of ultraviolet (UV) protection.
This technique is often used as
swimwear for children.
some textiles and fabrics employed
in the use of sun protective clothing
may be pre-treated with UV
inhibiting ingredients during
manufacture to enhance their UV
Some hats and umbrellas,
particularly for children may also use
A pressure sensor measures pressure, typically of gases or liquids
Pressure is an expression of the force required to stop a fluid from
expanding, and is usually stated in terms of force per unit area
Pressure sensors are used for control and monitoring in thousands
of everyday applications.
Pressure sensors can also be used to indirectly measure other
variables such as fluid/gas flow, speed, water level, and altitude.
Pressure sensors can vary drastically in
technology, design, performance, application suitability and cost.
Smart Shirt Architecture
Weave with optical
Sensitive to external
fields (ph, radiation,
mechanical fields). PASIVE
(usually form) as
response to external field changes
Characteristics of Smart Fibers
Blend with human tissue
Communicate,Locate and Monitor
Upto 0.6mm thick
Mobile technology cells
Human muscle movt
Some are 100% fabric
Can be crumpled /compressed (driven over)
Can handle extreme conditions
Enables the creation of touchpads
with any number of controls
In any layout
Supports gesture controls
& Scroll functions
256 spectrum of colors
Blend with human tissue
BCI(Brain Computer Interface)
A brain–computer interface (BCI), often called a mind-
machine interface (MMI)
BCIs are often directed at assisting, augmenting, or
repairing human cognitive or sensory-motor functions.
Communicate, Locate & Monitor
Army, Police, disaster response units
Giving more stability
Increase power by 25 – 35%
Carry wounded soldier
Platform for more/heavier weapons
Merits of smart fabrics
Integratable with fabric/human body
Cotton, Polyester, Nylon, etc
BCIs & Exoskeletons
Set to display the 256 spectrum
Seeable from a distant
Police & emergency services
Army, police etc
Space explorers & tourists
Demerits of Smart Fabrics
Some of the demerits are as follows
Charged & recharged
yet to be commercially realised
Need a battery pack
