These smart clothes communicate wirelessly over the internet to provide advanced services.
2. Literature Review
The research will be conducted using a descriptive-analytical method to address the problem.
To begin with, this article assumes that designing functional clothing involves two main stages: conducting user-oriented research and identifying their needs. Therefore, the design specifications vary for each design.
The advancements in technology today have revolutionized the alterations made to garments.
Smart clothing and textiles have gained increasing interest from fashion enthusiasts times. The use of digital products, including smart clothes, is rising steadily due to technological advancements. Throughout history, the primary purpose of textiles has been to safeguard the human body against diverse environmental elements like sunlight, wind, rain, etc. Smart and aesthetically pleasing fabrics have been introduced in clothing manufacturing in the current era. These intelligent textiles serve the purpose of safeguarding individuals in harsh weather conditions, and aiding in the prevention, monitoring, and occasionally even treatment of injuries or illnesses.
2.1. What does the term smart textile mean?
E-textiles, known as Electronic Textiles, are fabrics incorporating digital and electronic components like batteries, sensors, circuits, and small lights woven or embedded into the fabric, depending on the specific tool. The unique characteristics of these textiles have made them popular among individuals interested in fashion and technology. Smart textiles can respond to environmental, thermal, mechanical, chemical, biological, and magnetic cues. Additionally, they can establish connections with other smart devices through Wi-Fi or Bluetooth technology. Smart textiles enhance fabrics and clothing with added functionality. These textiles, including fibers, threads, and yarns woven or knitted into fabrics, interact with the environment or the wearer. Integrating electronics creates e-textiles, further advancing smart materials and providing improved benefits for the user.
2.2. Smart fabrics
Smart fabrics are materials that can respond to their surroundings. They are capable of activating digital and electronic components. Pyles-Friedman from the Pratt Institute explains that what sets smart fabrics apart is their capacity to perform tasks that traditional fabrics cannot, such as communication, transformation, energy management, and even growth. Smart textiles are designed to be sensitive and responsive to environmental conditions or specific mechanical, thermal, chemical, and electrical stimuli. To be considered smart textiles, they must consist of three essential components: sensors, actuators, and control units. The introduction of smart textiles has posed numerous challenges across various fields, including medicine, sports, military, and aerospace.

Figure 2. Smart functional textiles and clothing |
2.4. All types of intelligent fabrics
1. Passive smart materials: This category comprises materials that solely recognize environmental conditions or stimuli, such as changes in color, shape, thermal properties, or electrical resistance.
Example: A heat-resistant shirt that can monitor body temperature.
2. Active smart materials: can respond to external conditions or stimuli. By incorporating actuators into the passive smart textile component, they transform into active smart fabrics, allowing for a specific response to a given stimulus.
Example: The fabric of a shirt is sensitive to the surrounding temperature. When exposed to high temperatures, the shirt automatically pulls up its sleeves.
3. Smart materials: These materials exhibit a trifecta of functions. Firstly, they possess sensors capable of receiving signals. Secondly, they can react based on the received signals. Finally, they can change in shape, size, color, or action according to the function.
4. Highly materials transfer artificial intelligence to computers, a capability beyond human research. Achieving this requires research and development in textiles and electronics, specifically through smart fabrics or advanced materials that align with computer technology.
2.5. Three categories encompass smart textiles
• Textiles that consist of circuits, batteries, or LEDs.
• Diodes, wires, conductive fibers, and solar cells are directly integrated into the fibers of advanced electrical textiles.
• Smart textiles that combine elements from the types as mentioned earlier.
2.6. Intelligent wearable fabrics
Smart wearable textile products can engage, communicate, and comprehend due to the materials used in their production.
- Metal fibers are utilized.
- Conductive ink is employed.
- Chromic material is incorporated.
- Coating with nanoparticles is applied.
- Organic semiconductors play a role.
- The materials possess both shape and the capability to store memory.
- Optical fibers are included.
- Quantum tunneling composites are utilized.
- Intrinsically conductive polymers are incorporated.
Yarns are predominantly utilized in technical sectors, including apparel, military gear, medical applications, and electronics manufacturing. Conductive materials are combined with metallic or natural fibers to create conductive fibers. Fabric sensors are produced using stainless steel threads, metallic silk, organza net, and special carbon fibers. Moreover, materials such as metal polymers, conductive polymers, optical fibers, electrical conductivity, quantifiable sensors, and data transmission are employed. These flexible materials are characterized by elasticity, lightness, affordability, and ease of processing.
2.7. What is the difference between electronic textiles and smart textiles?
Nowadays, the world has various interpretations of the term "electronic textile." It can also be referred to as "integrated electronic textiles."
• The concept of electronic textiles involves the fusion of conventional fabrics and fibers with electronic components.
• By utilizing electronic textiles, it becomes possible to transmit various types of data, such as heat, light, motion, and sensory information regarding local conditions.
• Integrated e-textiles are primarily intended for wearable devices, although they can also have other applications.
• Alternative definitions approach the concept differently, stating that e-textiles are electronic threads specifically designed to integrate with a particular textile product.
2.8. Two main types of e-textiles
• Electronic components are integrated into fabrics, creating embedded electronic textiles. This particular product resembles a textile product rather than an electronic one.
• Multi-layer electronic fabrics are applied onto a non-textile material and then affixed or sewn onto the fabric's surface. These products may appear more akin to electronic items rather than textiles.
2.9. Smart textiles
ASTM International distinguishes between "e-textiles" and "smart textiles" by their definitions. Regarding functionality, "e-textiles" possess an electronic component, while "smart textiles" may have a mechanical reaction without an electronic element. A fabric such as thermochromic fabric, which changes color based on temperature, is an example of a smart fabric that does not fall under the "e-textile" definition. Furthermore, a smart fabric composed of suitable materials can modify its structure and regulate airflow, enhancing the comfort of the clothing during movement and in diverse environmental situations.
2.10. The objectives of electronic textiles and smart textiles
The main objective of e-textiles and smart textiles is to develop completely new categories of products. Unlike traditional forms, e-textile wearable technology and smart textiles do not need PCBs or other bulky hardware components; instead, sensors and circuits are directly integrated into the clothing. Several e-textiles and smart textiles have the potential to revolutionize clothing and other markets, including products such as a shirt that monitors an athlete's heart rate during exercise and works in conjunction with a smartphone app. • Wearable medical devices that are small, lightweight, and fashionable, designed to monitor health metrics such as blood oxygen levels and alert the medical team automatically in case of any problems.
• Clothing made of e-textiles that offer guidance on maintaining proper exercise form to athletes based on their speed, posture, and stress levels.
• Children's backpacks are integrated with location tracking and other features for enhanced safety through smart fabric technology.
• Clothing and accessories using smart textiles that can change color or patterns depending on factors like the wearer's condition, external temperature, or the current season.
• A winter jacket with an incorporated heating element in its interior, showcasing smart textile innovation.
These examples demonstrate how e-textiles counteract smart fabrics and fibers. E-textiles possess smart capabilities but rely on the computing power of smartphones or tablets by utilizing connectivity. In contrast, smart fabrics lack this information and instead have a reactive and passive role, only enabling users to activate or deactivate functions. For instance, a jacket with integrated heating does not require a smartphone connection, whereas performance shirts that track hydration and blood oxygen levels need to be connected to a separate device to access and utilize the gathered data.
2.11. The instruments utilized in electro textiles
Smart textiles are created using various tools, including diodes, batteries, circuits, wires, GPS technology, LEDs, and conductive metals.
Use of LED:
Smart textiles often incorporate bright LEDs illuminating in the night darkness leading to a captivating spectacle. This can be observed in the attire of ski athletes, for instance.
Using GPS:
The utilization of GPS in creating intelligent apparel is widely prevalent, as evidenced by clothing accessories that incorporate GPS technology. This technology is employed to locate these devices.
Both types of e-textiles offer numerous benefits:
• E-textiles can render sensors and computers flexible, lightweight, wearable, comfortable, and fashionable.
• Electronic filaments have the potential to be virtually imperceptible, allowing users to experience a high level of sensitivity.
• Recent advancements in fabric technologies concentrate on enhancing resistance to crushing and impact damage and increasing the flexibility and durability of embedded circuits.
2.12. Chemical-optical sensors
Chemical sensors, as per the Cambridge definition, can be defined as miniaturized devices that can provide online information about the presence of ions or specific compounds, even in complex samples.
The main aim of a chemical sensor is to generate measurable signals that correspond to a particular concentration of a compound in the surrounding environment. Typically, a chemical sensor consists of two components: the sensor or receiving part, and the conversion unit.
Optical sensors work on various principles such as absorption, reflection, radiation, fluorescence, refractive index, thermal-optical effects, and light scattering. Transducers in the sensor segment emit light upon contact with a specific analyte. An examination of the composition and effectiveness of chemical sensors
In general, chemical-optical sensors can be categorized into two main subgroups, namely direct-type sensors and detector-mediated sensors. When it comes to direct optical sensing, the analyte is detected directly based on its inherent optical characteristics like absorption and emission.
2.13. Fiber-optical chemical sensors
Fiber-optical chemical sensors belong to the category of chemical sensors. Typically, they can be classified as either intrinsic or non-intrinsic. In non-intrinsic sensors, optical fibers are commonly employed to transmit electromagnetic radiation to the sensor directly in contact with the sample.
Optical fiber sensors involve altering the optical fiber configuration and utilizing the fiber as an integral component in the sensing process. The optical fiber is a cylindrical cable with a diameter varying from under 1 micrometer to several hundred millimeters. Plastics, glass, and quartz are the predominant materials employed in fiber production. The prevailing sensors are typically non-intrinsic, comprising a chemical detector immobilized at the upper portion of a single or paired optical fiber. Alternatively, a chemical sensor can be affixed at the central region of the optical fiber to form an unsteady field sensor.Optical sensors offer advantages such as inexpensive optical fibers, enabling long-distance signal transmission without added complexity. Their compact size and flexibility also facilitate rapid data acquisition in challenging environments.
Removable sensors can be integrated into textiles using adhesive tape or sewing. Optical fiber sensors can be woven or layered into fabrics, effectively becoming part of the material. For fabrics designed to function as sensors, larger sensor surfaces are crucial. Consequently, chemical-optical sensors are applied via dyeing, printing, or coating. Detection relies on color changes, which can be observed visually, measured spectrophotometrically, or analyzed calorimetrically.
Recent advances have successfully integrated physical sensors for parameters like breath rate, heart rate, and temperature into clothing. Incorporating chemical sensors into fabrics introduces a novel dimension to smart textiles, offering valuable insights into individual health through the use of coated sensors.
2.14. Integration of an optical sensor in fabric
Various functions have been carried out in the textile industry to absorb sweat in clothing. However, incorporating chemical sensors into textiles is challenging. Therefore, addressing well-known issues related to wearable physical sensors, including physiological, environmental, and motion disturbances. Furthermore, chemical sensors have additional requirements due to their sensing mechanisms. The primary concern with sensor materials such as dyes, polymers, residual solvents, and additives is their potential toxicity. Additionally, when the sensor is directly in contact with the skin, it should not cause any reaction or harm to the skin. Moreover, the sensor should not pose any concerns or risks for users.
2.15. Use of metal fibers
Metal fibers significantly impact the field of E-Textiles and the textile industry. One notable example is Lame fabric, a blend of nylon and metal fibers. The reflective and glossy appearance of Lame fabric is attributed to metal fibers, while its elasticity is due to the presence of nylon.
2.16. Use of conductive metals
Conductive fibers known as Fibertronics are the product of combining metal and textile fibers, enabling them to possess conductivity or semi-conductivity. To achieve this, these fibers are blended. Their versatility allows them to be woven or sewn into the fabric, making them ideal for creating conductive properties in smart textiles. Moreover, Fibertronics are significantly lighter and more pliable compared to metal wires. Among the various applications, one notable use of these fibers is in designing police uniforms that offer protection against electric shocks. The concept of "smart material" was initially coined in Japan in 1989. The first textile material recognized as a smart textile was silk thread.
2.17. Smart clothes
Advancements in both fashion and technology have led to unique opportunities within the fashion industry. The aim of E-Textiles researchers is to create and design intelligent, adaptable, flexible, and comfortable garments similar to everyday clothing. As previously noted, smart fabrics are innovative textiles incorporated with technology. Initially, these fabrics attracted attention in the fashion world due to their ability to change color and lighting. However, over time, there have been significant improvements in these fabrics. Today, these garments feature technologies that allow communication with smartphones and other smart devices.
