SMART TEXTILE Smart materials or textiles can be defined as the materials and structures which have sense or can sense the environmental conditions or stimuli . whereas intelligent textiles can be defined as textile structures which not only can sense but can also react and respond to environmental conditions or stimuli. These stimuli as well as response, could be thermal, chemical, mechanical, electric, magnetic or from other source. Three components may be present in smart textiles (materials). Sensors, Actuators and Controlling units.
SMART TEXTILE INTRODUTION Textiles are considered as the second skin of humans . Protection and aesthetics are two common dimensions associated with textiles . Third dimension-intelligence is being integrated into fabrics to produce interactive textiles . Last few decades have shown enormous growth in the development of wireless communication, nano-engineering information technologies and miniaturisation of electronic .
CLASSIFICATION OF SMART TEXTILE I. Passive Smart Fabrics Can only Sense the environmen t. These are sensors. II. Active Smart Fabrics Can Sense and react to the environmental stimuli. These are Actuators and sensors. III. Ultra Smart Fabrics Can Sense, react and adapt themselves to env ironment . Cognition, reasoning and activating capacities .
PASSIVE SMART TEXTILE Passive Smart Textiles are materials with a textile nature that can be included in a textile structure. This also means that these fabrics don’t contain sensors or wires. They do not need to change because of the conditions around them. Passive Smart textile is the first generations of smart textiles, which can only sense the environmental conditions . which can only sense the environmental condition or stimuli. Wearable sensors fall in this category viz built-in GPS,clothing integrated baby breathing monitors and clothing that gives potential changes about weather. Some examples are UV-protective clothing, multilayer composite yarn and textiles, plasma-treated clothing, ceramic-coated textiles, conductive fibres, and fabrics with optical sensors.
ACTIVE SMART TEXTILE when clothing not only senses the environment but also reacts to the condition or stimuli. Examples include clothing that changes density depending on the temperature outside which can sense, react and adapt themseives accordingly Example: space suit which can sense the outside temperature and adapt accordingly. These include electrically heated suits, shape-memory clothing, chameleonic materials, water- and vapor -permeable (hydrophilic/non-porous) fabrics, heat-storage fabric, thermo-regulated fabric, vapor -absorbing fabric, and fabric with shape memory. Made of Phase change materials and shape memory materials, heat sensitive dyes et c in textiles form active smart textiles.
ULTRA SMART TEXTILE Ultra smart textiles are sophisticated with monitoring, reacting to the collected data, and adapting the function depending on the wearer’s need. It is also known as Very smart textile. It is the third generation of smart textiles, which can sense, react and adopt themselves to environmental conditions. A very smart textile essentially consists of a unit. which works like the brain, with cognition, reasoning and activating capacities. which are those capable of responding or activated to perform a function in a manual or preprogrammed manner.For example shirts that can store information through a built-in fabric keyboard and send it via bluetooth to a computer.
SMART TEXTILE FUNCTION The smart textile has five functions to complete its full work. They are- Sensors- It capture parameters from the environment Data Processing- It is required when active processing is necessary Actuators- It respond by the resulting function of the sensor Stimulation - It is found in the environment Giving Response- From the actuators, it gives a response
APPLICATIONS OF SMART TEXTILE Smart textiles have a wide spectrum of applications ranging from daily usage to high-tech usage. Now we can review various important applications of such textiles. We would consider textiles used for the following broad categories: Comfort wear
Heat protection
Medical applications
Safety and Military applications
Computing textiles
Fashion and Footwear
Aviation
Space research Entertainment Transportation Sports and Fitness
Health care Smart textile is already used for health care. The high technology in textiles gives us the opportunity for Personal Health care. The development of wearable monitoring systems is already having an effect on healthcare in the form of Telemedicine. The concept of personalized healthcare empowers one’s own healthcare. Wearable devices allow physiological signals. Thus daily life becomes so much pain free. Life belt plays a significant role in medical sector. It’s a valuable decision support tool. Like life belt life jacket is also a medical device which always monitoring blood pressure or the heart rate. All the information is transferred to a computer and which is read by a medical staff.
SHAPE MEMORY TEXTILES Materials capable of remembering the original shape are called shape memory materials.
Materials are shaped out of its original shape as the temperature change returns to its original shape with a chemical, mechanical, magnetic, or electrical external effect.
There are many classes of shape memory materials such as alloys, polymers, gels, and ceramics.
These materials exhibit novel properties such as sensing (thermal, stress,optical , chemical), actuation, high damping, adaptive responses, super- elasticitycapability and air permeability.
Shape memory alloys are composed of a combination of two or more elements with the properties of hardness and elasticity that vary considerably at certain temperatures.
Shape memory polymers can be used in fiber production or can be applied to the fabric by finishing, coating, or lamination processes.
They are used in medical, textile,garments and footwear products, composites and electrical appliances.
WEARABLE SMART ELECTRIC TEXTILE The four basic elements of wearable smart electronic textiles are conductivity, sensors, wireless communication module, and power supply. A new report from Cientifica Research examines the markets for textile-based wearable technologies The report identifies three distinct generations of textile wearable technologies: "First-generation" attach a sensor to apparel. This approach is currently taken by sportswear brands such as Adidas, Nike, and Under Armour "Second-generation" products embed the sensor in the garment, as demonstrated by current products from Samsung, Alphabet, Ralph Lauren, and Flex. In "third-generation" wearables, the garment is the sensor. A growing number of companies are creating pressure, strain, and temperature sensors for this purpose.
PHASE CHANGING MATERIAL Phase change materials, with a textile substrate, are basically thermo regulating materials. ThermoBall is a functional product that contains phase change material (PCM) within microcapsules. It absorbs heat as the surrounding temperature rises and gradually releases heat as the temperature decreases. When applied to bedding and clothing, ThermoBall microcapsules undergo phase change in response to temperature fluctuations in the external environment or changes in body temperature. This enables them to absorb or release heat, offering a cooling or thermal insulation effect that enhances thermal comfort and provides a sense of relaxation and comfort
COLOUR CHANGING APPLICATION They are intelligent textile materials that have the ability to change color with an external stimulus effect.
To create the transformative textile, the fabric is soaked in chromic dyes, pigments, or covered in a chromic coating. Color -changing materials are chromic materials or chameleon materials. Color changing materials are specified according to the effect mechanism.
Light, heat, pH change, solution, friction and pressure are basic effect parameters.
They are also called by the effect type as photochromic (light effected), thermochromic (heat effected), electrochromic (electric effected), solvent chromic (solution effected), halochromic (pH effected), tribochromic (friction effected), mechanochromic (pressure effected). Color -changing clothing provides a new way to express creativity and personality. We can use the color -changing effect to create unique patterns on textiles, making clothing uniquely artistic and personalized, bringing creative, interesting and practical clothing to people.
MILITARY CLOTHING The smart textiles for the military market are experiencing significant growth and innovation, driven by advancements in material science, nanotechnology, wearable electronics, and increasing demand for enhanced soldier performance and safety.
Modern militaries are looking to equip their soldiers with advanced systems to enhance their situational awareness, survivability, and overall effectiveness on the battlefield.
Soldiers dress in thick layers and lots of tactical gear. Not only does it take a lot of effort to carry, but it also poses a need for portable power sources. Batteries are carried, along with their gear, and disposed of quickly. Without ample power, the equipment becomes unusable. Smart Textiles For Military improve performance of soldiers offering them more mobility and fast connectivity. Military fabrics are made from more than just your standard fabrics like cotton or canvas; they are also made from things like polyester, vinyl, polyester vinyl composites, and acrylics to name a few.
