Humidity-Responsive Fabric Changes Heat Flow

Humidity near your skin can change how a prototype fabric releases body heat. University of Maryland researchers reported this laboratory textile in 2019. Humidity near skin changes its composite yarn. One fiber absorbs water while another repels it. The fibers warp, yarn strands draw closer, pores open, and infrared heat transfer changes. The process is passive. This textile has no electronic sensor, processor, or brain. The study shows a materials mechanism, not a retail shirt or guaranteed comfort. Outdoor work and sportswear are possible applications. The study did not prove performance across all climates or that one outfit can replace seasonal clothing. Tiny muscles and tiny brain are analogies. The warming world statement is future facing. The wrist to ribs line refers to a broader smart textile trend, including separate MIT fiber computer research. #MaterialScience #SmartTextiles #CarbonNanotubes #ThermalRegulation #AppliedPhysics University of Maryland research https://energy.umd.edu/news/story/scientists-develop-first-fabric-to-automatically-cool-or-insulate-depending-on-conditions Published study https://pubmed.ncbi.nlm.nih.gov/30733415/ University of Maryland technology overview https://www.umventures.org/technologies/nanotube-enabled-thermoregulation-fabric Separate MIT fiber computer research https://dmse.mit.edu/news/fiber-computer-allows-apparel-to-run-apps-and-understand-the-wearer/ Photo by Karolina Grabowska www.kaboompics.com on Pexels https://www.pexels.com/photo/close-up-blue-textile-background-6292/ Music by Alex Morgan, Downtempo Chill Electronic, from Pixabay https://pixabay.com/music/beats/downtempo-chill-electronic-528322/ I have created this video using the digital twin of my original video and my original voice.
