At present, the smart textile market is becoming a new engine of global economic growth. According to market Research, the global smart textiles market is expected to grow from $2.52 billion in 2021 to $9.3 billion in 2026, with a compound annual growth rate of 28.7%. Another data is expected that the smart wearable textile market will grow rapidly in the next few years, and the market size is expected to reach 144.725 billion yuan by 2028.
The application field of intelligent textiles is very wide, and the application prospect is very considerable. Including medical health, sports and fitness, military, home and other aspects. For example, in the military field, ultra-micro sensors can be embedded in combat uniforms to monitor soldiers' health, provide real-time data support, and also identify soldiers' injuries during combat. In the field of sports fitness, smart textiles can also integrate various sensors to monitor the wearer's exercise intensity, energy consumption, heart rate, respiratory rate and other key health parameters. For example, the smart sports bra launched by some brands has a built-in heart rate belt, which can monitor the wearer's heartbeat in real time, detect heart rate, breathing, activity intensity, blood pressure and other data, and connect to the mobile terminal through Bluetooth.
In addition, many well-known brands and startups are actively developing smart sportswear, such as Nike, Adidas, Victoria's Secret and so on.
The application of flexible materials is becoming more and more important. These materials can be attached to the surface or interior of textile materials by spinning, spinning, coating and other technologies to obtain conductive textile materials.
The development of new smart textiles is also inseparable from the innovation of materials. For example, the stretchability, breathability and durability of smart electronic fabrics, as well as washability, bendability and so on, have a lot of room for improvement. At present, researchers in the textile field are also developing adaptive, sustainable and biocompatible smart materials, such as conductive fibers, shape memory materials, nanomaterials and so on.
Despite the broad prospects of the smart textile market, it also faces many technical challenges, mainly in the following aspects:
One is integration and function realization. The integration and control of complex functions while keeping textiles light and comfortable is a major challenge. How to effectively integrate electronic components such as sensors and circuits into textiles and maintain their stability and durability without affecting the wearing experience is one of the current technical problems.
The second is the compatibility of materials and electronic devices. How to organically combine the flexibility of traditional textiles with the rigidity of electronic products, and at the same time, how to ensure that these materials do not deteriorate in the long-term use of the process is also an urgent problem to be solved.
The third is sensing technology and data processing. The key to the application of smart wearable textiles in health monitoring, motion tracking and other fields is to improve the precise sensitivity of sensor parts and accurately capture relevant data.
Fourth, environmental impact. The production and use of smart textiles may have a certain impact on the environment. How to achieve green production and reduce the negative impact on the environment is one of the important challenges in the development of smart textiles.
Fifth, resource recovery and reuse. With the popularity of smart textiles, the problem of waste treatment and recycling has become increasingly prominent. How to establish an effective resource recovery and reuse mechanism to reduce resource waste and environmental pollution is the key to the sustainable development of smart textiles.
To address these issues, researchers are developing better machining accuracy and efficient layout designs to improve mechanical and electrical stability, wear comfort, safety and ecological sustainability of products.
