Innovation Area:

TomKat Center-supported
Internship Term: 
8 weeks

IRCool Textiles is developing infrared (IR) radiative cooling fabrics based on photonic structure textiles. These unique designs allow the radiative heat emitted by the human body to dissipate efficiently and thereby cool down the body more effectively than do current textiles. The pioneering radiative cooling textile research leading to this technology was initiated at Stanford and resulted in the first experimental demonstrations of radiative human body cooling using textiles, and the first knitted and woven photonic structure textiles with enhanced cooling performance based on efficient radiative heat transfer. We are currently working to bring this cooling textile technology to the next level of commercialization, which includes fabricating large-scale woven fabric samples with optimized weaving and knitting patterns, and applying textile finishing processes without affecting cooling performance.
