Printed Fabric Heaters Integrated Smart-Apparels

CSIR-NIIST has developed advanced smart apparel with thermoregulation capabilities using printed electronics technology, designed for the next generation of intelligent clothing. By depositing conductive materials in ink form onto flexible substrates, we have created printed heaters that deliver efficient heating while consuming minimal electrical energy. These heaters offer a lightweight and flexible alternative to conventional coil heaters and can be seamlessly integrated into various wearable applications, such as heated insoles, gloves, and jackets. Our innovation focuses on three primary types of heated apparel: insoles, gloves, and jackets. The heated gloves are produced by incorporating fabric heater into commercially available gloves, customized to meet specific warmth requirements. Similarly, the heated insoles are developed by combining a printed heater with a standard polyurethane base and fusible interfacing fabric, ensuring comfort and functionality equivalent to traditional insoles. In extremely cold climates, where conventional jackets struggle to provide sufficient warmth, our heated jacket offers a highly effective solution. These jackets are equipped with integrated fabric heaters that regulate body temperature based on user preferences, eliminating the need for rigid components and enhancing comfort. The result is a versatile, energy-efficient line of smart clothing that not only improves user experience but also meets the demands of those working in harsh conditions. These smart apparels are well suited for defence personnel operating in cold desert environments.
