NTU's research in electronic textiles is having a significant impact on the health, sports, defence and fashion sectors. Five of the products developed by the research now have worldwide patents, demonstrating evidence of their impact.

The most significant examples of products which are having an impact are:

  • the manufacture of second-generation electronic textiles in the form of knitted garments for older people which are used for vital sign monitoring
  • the development of a conductive suit
  • the development of electrically heated gloves
  • a new test for a hip protector system.

In the past decade there has been a lot of commercial interest in electronically active smart textiles. Business Wire claims that market growth in the sector is estimated at 21.54% annually from 2013 to 2018, and is expected to reach over $2 billion by 2018. As a result of the commercial potential, there is intense worldwide research interest in electronically active textiles, but only a very few research groups specialise in specific technical aspects.

The broad scope of NTU's research group and its focus on fusing scientific, engineering and design disciplines to create novel and innovative electronically active smart textiles make their research unique internationally. The smart yarn technology developed by NTU has provided a robust functionality that is resistant to wear, washing and drying and can be produced at lower costs than other electronic textiles where functionality is often added at the garment stage. As a result, NTU's products have a significant impact on the production and use of electronic textiles in clothing applications.

The following advanced textiles products developed by NTU have been patented since 2010:

Health monitoring garments

Research on knitted transducers exploits the technology in a range of sectors for remote condition monitoring of heart rate, breathing patterns and skin temperature. The devices, developed through the findings of NTU's research, transmit data wirelessly in real-time for analysis.

Defence sector: Electrically conducting suit (MoD)

The Ministry of Defence conducted experimental trials on a seamless knitted garment designed and made from electrically conducting yarns by Dias' team, applying the knowledge in patent. The details and the outcome of the trials cannot be disclosed.

Sports sector: Heated glove liner

Professor Dias and his team designed a knitted glove liner with five heating elements and conductive pathways. The team also developed the technology to manufacture the knitted glove liner on a commercial scale.

The team is developing further products for the management of Raynaud's disease.

Health sector: 3D spacer fabrics for use as hip protectors

NTU's researchers developed a test method for screening the hip protectors.

Research background

NTU's research in advanced textiles dates back to 1980 and is based on expertise in textile fibre materials, digital textile manufacturing processes and garment making.

In 2008, the School of Art & Design recognised the importance of designing electronically active advanced textiles for wearable systems. This led to the research team bringing together expertise in knitting, weaving, embroidery and garment construction to develop textile stretch sensors.

The research base was strengthened by the arrival of Professor Dias, who joined in 2010 to lead the Advanced Textiles Research Group (ATRG).

Dias has led research to understand the electrical properties of knitted structures when they undergo static and dynamic deformations. The knowledge generated by this research has a practical application in the development fibre-based transducers for wearable computing and in the next generation of SMART clothing. The SMART clothing enables measurement of the vital signs of the body: ECG, breathing rate, breathing patterns, skin temperature, perspiration, bodily electrical activity, body motion and gesturing. The potential of health monitoring clothes to improve the quality of life and health outcomes for patients and the elderly is immense.

The demand for the form of transducer developed by Dias and his team arose from the limitations of the first generation of smart clothing, which used rigid sensors bolted on to the garment using traditional textile processes such as sewing and gluing. The fabric transducers developed at NTU incorporate the electro-conductive fibres in the non-conductive base structure during the fabric manufacturing process, which make second- generation smart clothing possible.

Professor Dias' team has developed applications for these devices in smart clothing partnership with Loughborough University, the University of Sheffield and the University of Salford

The team's research identified major challenges in second-generation technologies for smart clothing caused by the inherent hysteresis of textile structures which limits their application to only relative measurements. Truly smart textile structures and clothing must be able to carry out absolute measurements, analyse data and respond accordingly. To address this problem, from 2010 the team began to research the possibility of embedding semiconductor micro devices into fibres and yarns, using a conformable polymer resin to bind the chip with the fibres of the yarn.

The objective is to position encapsulated chips along the length of the yarn at predetermined intervals without compromising fabric manufacture. The encapsulation hermitically seals the chip, protecting it from all forms of stress (mechanical, thermal and chemical). This produces intelligent electronic yarn capable of physical sensing, signal processing, transmitting and receiving. This intelligent yarn will form the basic building blocks of truly flexible, drape-able and washable textile computers in the near future, creating third generation wearable computing.
