Abstract E-textiles that integrate multifunctional materials into clothing hold great potential for the wearable electronics market. One of the ultimate objectives of wearable electronics is their integration with textiles and clothes so that device functions can be conducted along with the textile advantages such as comfort, breathability, soft fabrics, and high sustainability. Various components of electronic devices like textile circuits, light-emitting diodes, and a variety of sensors for pressure, temperature, and vital signs have been used in smart clothing. There are also some prototypes of flexible, textile-based, energy-storage devices such as batteries, supercapacitors, and direct-power generations that sustain these devices, which are integrated into clothing. These wearable technologies have potential applications in sportswear and could change athletes’ experience during sports considerably just like smartphones, tablets, and other gadgets have in the recent past.
