What are e-textiles, and what is the difference between e-textiles and smart textiles?

What are e-textiles?

E-textiles, or electronic textiles, as it stands for, are fabric that you embed electronic components in. Any electrical component can theoretically be embedded, but commonly used in e-textiles are sensors, lights, and batteries.

What is the difference between e-textiles and smart textiles?

Though e-textiles and smart textiles are often used synonymously, they are not the same. Smart textiles are fabrics with added functionality for the wearer. This can be an electronic component and is nowadays often the case but not always. You can read more about smart textiles in this article. E-textiles, on the other hand, presume some electronics are embedded in the fabric to be called e-textiles.

In other words, smart textiles have a broader definition and thus include many more types of textiles than e-textiles, which have a relatively narrow definition. However, smart textiles of the second and third generations are more or less the same as e-textiles and always include electrical signals of some sort.

The different types of e-textiles

Similar to smart textiles, e-textiles are divided into three generations:

  • In the first generation, sensors are attached to garments commonly used in several sports brands.
  • In the second generation, sensors are instead embedded in the garment.
  • The third generation goes one step further, using the garment as the sensor.

E-textiles build-up

Depending on which generation of e-textiles you're exploring, the construction and integration of electronic components can vary significantly. First-generation e-textiles involve attaching sensors, lights, or other electronic elements onto the fabric's surface. This approach, while innovative, can sometimes compromise the fabric's flexibility and comfort. 

Second-generation e-textiles address this limitation by embedding the electronic components directly into the fabric. This integration allows for more seamless and flexible designs, enhancing the textiles' aesthetics and usability. However, challenges like washability and durability often need to be overcome to ensure the longevity of these garments. 

The third generation of e-textiles pushes the boundaries even further by turning the fabric itself into a sensor, opening up new possibilities for interactive and responsive textiles.

Either way, the build-up is the same as for the second and third generations of smart textiles:

  • Fabric
  • Conductive material of some sort to lead electrical signals
  • Sensors
  • PCB or connector as it often is referred to, especially in combination with a battery pack
  • Battery (these are often packed together with the PCB)

What are e-textiles used for?

E-textiles offer a wide array of applications across various industries. In fashion, they enable designers to create stylish garments that respond to environmental factors or the wearer's movements. Medical e-textiles have found their way into healthcare, facilitating real-time monitoring of patient's vital signs through unobtrusive clothing. Sports and fitness enthusiasts benefit from e-textile sportswear that tracks performance metrics, providing valuable insights for training optimization. Additionally, e-textiles have applications in the automotive and aerospace industries, where they can enhance the comfort and safety of vehicle interiors. The fusion of electronics and textiles opens the door to innovations that blur the line between technology and everyday clothing.

Challenges in the e-textile industry

Despite the exciting opportunities e-textiles bring, the industry faces several challenges. Ensuring the durability of electronic components within textiles is a critical concern, as garments need to withstand washing, stretching, and everyday wear and tear. The integration of electronics also demands attention to safety and comfort to prevent irritation or potential health risks for the wearer. Furthermore, the complexity of manufacturing e-textiles can lead to higher production costs, affecting their accessibility to a broader audience. Addressing these challenges requires collaboration between textile experts, electronics engineers, and other specialists to create reliable, functional, and user-friendly e-textile solutions.

Where LumeoTech comes in

LumeoTech specializes in creating connectors for smart textile and e-textile garments, solving the industry's challenges. The unique feature of LumeoTechs connectors is that they attach and detach in seconds, solving the issue of easiness for both customers and manufacturers, minimizing the time to produce the garment, and cutting the cost.
