One of the major challenges in wearable technology is overcoming the constraints imposed by traditional battery shapes and sizes. Despite advances in other areas, most wearable devices still rely on rigid batteries that limit design flexibility. However, a breakthrough has recently been made by researchers in the United States who have developed a flexible, textile-based battery. This innovative power source can not only supply energy to wearable gadgets but also bend and stretch like regular cotton fabric, offering new possibilities for smart clothing.
Nazmul Karim, a researcher at the University of Manchester, was part of this groundbreaking project. He explained that the development of this flexible battery marks a significant step forward in creating smart fabrics—materials that can integrate computing power directly into clothing. According to the team, this kind of battery could power wearable devices and allow displays to be embedded in fabric, improving both health monitoring capabilities and user comfort.
The flexible textile batteries are made using affordable graphene materials and manufactured through a simple screen printing process. The electrodes remain stable due to strong interactions between the ink and the fabric, ensuring safe and long-lasting performance. These batteries are also capable of fast charging and can withstand washing, making them ideal for everyday use in clothing.
The research team hopes their innovation will pave the way for future smart wearable computers and intelligent garments. They are currently finalizing their findings for publication. Meanwhile, the University of Manchester is investing £60 million in building a large-scale graphene production facility, set to open next year. This plant will serve as a global research hub for the International Graphene Institute, further advancing the field of advanced materials and wearable tech.
