The fabric has heat-conducting properties on par with stainless steel, researchers report.
As smartwatches become more powerful, they will generate more heat. To prevent burns or rashes, what if a material touching the skin could feel as cool as metal, but also be flexible enough to be worn on the wrist?
The hiking gear material is made of ultra-high molecular weight polyethylene fibers, which are sold commercially under the brand name Dyneema. These polymer-based fabrics are marketed for their high strength, durability, and abrasion resistance. They are often used to create body armor, specialty sports gear, ropes, and nets.
Heat transfer researchers recently investigated other uses for the fabric, namely as a cooling interface between human skin and wearable electronics. Their research is published in
