 With the new development of graphene in printed electronics, the usability of wearable technology continues to grow.

    Recently, the University of Manchester in the United Kingdom demonstrated a new technology solution: by using simple screen printing technology, printed device similar to the flexible battery directly on textiles, this technology solves the problem of wearable device charging. A component called Supercapacitor is a way to implement this solution. It functions like a battery and can be recharged quickly enough to charge the device in seconds.

    The availability of a solid flexible ultracapacitor device is now proven, with the specific operation of printing on cotton fabric using a conductive graphene ink. The media previously reported 2-DMaterials, a printed electrode that exhibits excellent mechanical stability due to the interaction between the ink and the textile substrate.

    The further development of graphene printed supercapacitors has sparked the great potential of wearable technology. After more in-depth research and development, such as high-performance sportswear monitoring human health conditions, light military equipment, new mobile communications equipment, and even wearable computers will become a reality.

    In order to charge these new wearable devices, the electrical energy storage system must have such features as high energy, high power density, good operational safety, long cycle life, low cost and mechanical flexibility.

    Nazmul Karim, Ph.D., researcher at the National Graphene Institute, said: "The development of graphene flexible fabric supercapacitors using simple, scalable printing technology is a significant step toward enabling the next generation of wearable electronic fabrics, Eco-friendly textiles that store energy and monitor human activity and physiology are eco-friendly and efficient. "

    Graphene oxide is a form of graphene that can be produced at low cost in an ink-like solution. This solution can be applied to textiles to create fabric supercapacitors.

    Amor Abdelkader, PhD, said: "For the first time, textiles have the characteristic of ductility and flexibility. For the first time, we have printed a stable device that stores both energy and flexibility. The device is also washable, which allows it to be used in the future Smart apparel and we believe this work will open the door to the printing of other equipment on textiles using 2-DMaterials inks. "

    The University of Manchester is currently building a Graphene Engineering Innovation Center to strengthen the research capabilities of the National Graphene Institute. The innovation center costs £ 60 million and will become an international research and technology base.

    Nazmul Karim, a researcher at the University of Manchester who is one of the inventors of the project, said flexible woven cells create a smart cloth that not only powers the wearable properly, but also be as flexible as ordinary cotton.

    The researchers said the flexible battery device, which powers the wearable device, will enable the wearable product screen to be used directly in clothing fabrics for better health monitoring and wearable display devices.

    According to the researchers, flexible woven cells are based on low-cost graphene materials and simple screen-printing techniques are used on the outside. The electrodes are very stable due to the strong interaction between the ink and the textile and have good operational safety Sex and long cycle life, the battery itself also supports fast charging, flexible materials allow washing.

    Researchers hope their findings will open the door to wearable smart computers and smart fabrics, and they are currently writing a research paper for the study. The University of Manchester is currently investing £ 60 million to build a large graphene factory, which will be completed by next year and will provide international research facilities to the International Graphene Institute (NGI).
