The technological revolution changing the world of fashion frequently because technology is shifting out from our hands to a sleeve of a garment. Wearable industry moving from wristwatch and headset to smart clothing. The main idea of my project was to design and produce garments that can serve a purpose. My project aimed to investigate e-textiles and smart clothing in the sports and fitness sectors and explore the impact of incorporating technology into activewear to enhance performance. To achieve my aim, I conducted an online survey to understand the wearable market, gaps, and possibilities of development in smart clothing. As a result, I designed and produced a waterproof activewear collection integrated with a fitness tracker POD for outdoor activities. This Performance Optimisation Device (POD) was placed inside the front chest pocket of the jacket for extra weather protection. This wearable sensor monitors exercise activities without any disruption.
