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 and actuators.

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 TextilesWearable electronic textiles are often controlled by soft

switches which are sewn into products using printing, coating and embroidery.

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 Sun protective

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 blocking capacity.

Some hats and umbrellas, particularly for children may also use this technique.

Pressure SensorsA 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 areaPressure 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.

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.
