  3. 3.  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 Fabrics
  4. 4. Artificial Horizon.  Direction Finding Low Radar Cross Section Antenna systems. Smart Fabrics in Electronics Collapsible Impulse Radiating Antenna.
  5. 5. Smart Fabric heater works on demand - heating is activated under pressure
  6. 6. 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.
  7. 7. Wearable Electronic Textiles  Wearable 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.

  9. 9. 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.
  10. 10. Pressure Sensors 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.
  11. 11. Smart Shirt Architecture  Electronic devices  Heart rate  Breathing  Body temperature  Electrocardiogram  Voice Weave with optical fibers net
  12. 12. Computers development Past times Today reality
  13. 13. Computer comfort Hard computers  hard  stiff  thick Textile computers soft flexible thin
  14. 14. Intelligent textiles  Sensitive to external fields (ph, radiation, electric, magnetic, mechanical fields). PASIVE  Changing properties (usually form) as response to external field changes ACTIVE electrochromic photochromic
  15. 15. Characteristics of Smart Fibers Light Durable Washable Versatile Blend with human tissue Communicate,Locate and Monitor
  16. 16. Light  thus portable  Soft  Upto 0.6mm thick  Powered by  Parent device  Mobile technology cells  Luminous fibres  Human muscle movt  Flexible  Some are 100% fabric  No wires/lumps  ’foldable’, ’creasable’
  17. 17. Durable  Can be crumpled /compressed (driven over)  Pierce resistant  Water proof  Can handle extreme conditions
  18. 18. Washable  Dry cleanable  Applicable in various garments  Nylon  Denim  Wool  Silicon  Cotton  Polyester  Plastics
  19. 19. Versatile  Enables the creation of touchpads  with any number of controls  In any layout  Supports gesture controls  & Scroll functions  Lit fabrics  256 spectrum of colors
  20. 20. 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.
  21. 21. Communicate, Locate & Monitor  Army, Police, disaster response units  Communication systems  GPS systems  Monitoring systems  Exoskeleton  Giving more stability  Increase power by 25 – 35%  Carry wounded soldier  Platform for more/heavier weapons  Enhanced armours  Lighter  stronger
  22. 22. Futuristic fashions  Clothing  Carnivore  Concerts  Personal accessories  Purses  Bags...  Furniture  Loose covers  Security & emergency  Rd construction  Police, fire brigaders, paramedics...
  23. 23. Merits of smart fabrics  Integratable with fabric/human body  Cotton, Polyester, Nylon, etc  Washable  BCIs & Exoskeletons  Color change  Set to display the 256 spectrum  Seeable from a distant  Police & emergency services  Construction
  24. 24. Tracking/communication systems  Army, police etc  wildlife  Monitoring systems  Army  Patients  Space explorers & tourists  Wildlife
  25. 25. Demerits of Smart Fabrics  Some of the demerits are as follows  Charged & recharged  Bulky  yet to be commercially realised  Need a battery pack  Expensive  BCI
