Future Intricacies and Potential of Smart Textiles

Wearable technology has been a game-changer in the healthcare industry. According to a report by Allied Market Research, the global wearable medical device market is projected to reach $27.4 billion by 2027.

From monitoring vital signs to tracking physical activity, wearable devices have allowed unprecedented insights into patients' health. However, the limitations of traditional wearables have spurred the development of a new generation of health-monitoring tools: smart textiles.

Intelligent textiles are designed to integrate sensors and electronic components directly into the material, allowing for continuous, unobtrusive monitoring of vital signs and other physiological parameters. Unlike traditional wearable devices, which can be uncomfortable and cumbersome to wear, smart textiles can be seamlessly integrated into everyday clothing or specialized medical garments, making them a versatile tool for healthcare professionals.

In this article, we’ll explore the intricacies and potential of smart textiles, focusing on the materials, technologies, and sensors involved in their development. We’ll also look at the applications of smart textiles beyond healthcare and discuss future advancements and challenges in the field.

Materials used in Smart Textiles

Smart textiles are made from a variety of materials, each with its own unique properties and applications. One of the key features of smart textiles is their ability to conduct electricity, which enables them to transmit data from embedded sensors. Conductive materials can be woven directly into the fabric or applied as a coating. Examples of conductive materials used in smart textiles include conductive yarns, metal wires, and graphene.

In addition to conductive materials, smart textiles may also incorporate other types of materials that enable specific functionalities. For example, stretchable materials can be used in wearables to improve comfort and flexibility, while waterproof materials can protect electronic components from moisture and sweat. Materials used in some forms of smart textiles are able to alter their appearance in response to environmental factors such as temperature and pH.

The choice of materials used in smart textiles can have a significant impact on their properties and performance. For example, a textile with a high degree of conductivity may be more effective at transmitting data from sensors, while a highly elastic material may be more comfortable to wear. As a result, researchers and manufacturers must carefully consider the properties of different materials when designing smart textiles. One emerging area of research in this field is the development of biocompatible materials that are safe to use in medical applications and can be worn directly on the skin.

Potential Applications of Smart Textiles

Smart textiles have enormous potential beyond healthcare and are already being implemented in various fields, including sports, fashion, and the military. Listed below are a few possible applications of smart textiles.

A. Sports Smart textiles have found their way into the sports industry in recent years, providing athletes with real-time monitoring of their physical activity. These textiles can track various parameters such as heart rate, breathing rate, and body temperature, providing coaches and trainers with valuable data to optimize an athlete’s performance. According to a report by ResearchAndMarkets, the global smart textile market in sports and fitness is expected to reach $5.5 billion by 2024, growing at a CAGR of 30.4% during the forecast period from 2019 to 2024.

Nike, for instance, has developed a smart sports bra equipped with sensors that monitor an athlete’s performance during workouts. Similarly, Under Armour’s “UA Athlete Recovery Sleepwear” uses bioceramic technology to aid in post-workout recovery. As Kevin Haley, President of Innovation at Under Armour, stated, “We are constantly exploring ways to empower athletes with new tools and insights that improve their performance and recovery.”

B. Fashion Smart textiles have also made their way into the fashion industry, providing designers with new materials and technologies to create innovative clothing and accessories.

CuteCircuit’s “Hug Shirt” uses Bluetooth technology and sensors to allow people to send hugs to one another from afar. As Francesca Rosella, co-founder of CuteCircuit, explained: “We want to add a new sense to our communication, the sense of touch, and by doing so, we want to enhance the emotional communication between people, to make people feel closer, even when they are far away.” When you contact the red places on the Hug Shirt, your phone gets the sensor data (hug pressure, skin temperature, pulse rate, time you’ve been hugging, etc.) through Bluetooth and sends it to the other person.

Google and Levi’s “Commuter Trucker Jacket,” which allows users to control their phone through touch-enabled fibers woven into the jacket’s sleeve, Paul Dillinger, VP of Global Product Innovation at Levi’s, stated: “our goal is to create a product that is so useful, you can’t imagine going through your day without it.”

Ralph Lauren’s “PoloTech Shirt” uses sensors to track the wearer’s heart rate, breathing rate, and other biometric data. As David Lauren, Executive Vice President at Ralph Lauren, said, “Ralph Lauren continues to be at the forefront of fashion and culture.” “Our goal is to create and reflect the ultimate lifestyle, and we believe that a healthy and active life is an essential part of that.”

C. Military Smart textiles have also shown potential in military applications, providing soldiers with improved protection and communication capabilities. For instance, the U.S. Army has developed a smart uniform called the “Integrated Warfighter System” that integrates sensors to monitor the wearer’s vital signs, body position, and environmental conditions. This uniform can also monitor the health and performance of soldiers in the field, allowing for real-time adjustments to be made. According to a report by Global Market Insights, the global smart textile market in military and defense is expected to reach $1.9 billion by 2025, growing at a CAGR of 11.7% during the forecast period from 2019 to 2025.
