A chilling effect on hot flashes

Ben Welter - Tuesday, December 09, 2014

CoolCami camisoleIs there any temperature-regulation problem that phase change material can't solve? CoolCami, a form-fitting camisole, is designed to reduce the discomfort of hot flashes. A cooling liner made from PCMs absorbs the heat generated by a woman's body when a hot flash kicks in. 

The CoolCami company also sells CoolMeMat, designed to provide relief for people who suffer from night sweats. The liners for both products recharge in about an hour at room temperature and provide relief for up to four hours.

You could even say it glows

Ben Welter - Tuesday, November 25, 2014

Rudolph Microencapsulation of PCMs typically involves a single purpose: thermal energy storage. What if you could make that material glow as well? That's what three researchers at the Beijing University of Chemical Technology set out to find. They designed and synthesized PCM microcapsules with an n-eicosane core and zirconium dioxide shell to attain the characteristics of latent-heat storage/release and photoluminescence. Potential applications include intelligent fibers and photosensitive devices.

Outlast introduces new PCM-based filler material

Ben Welter - Friday, November 14, 2014

Outlast Technologies’ new Universe climate-control material is designed for use in bedding and apparel. The material is a combination of 70 percent down and 70 PCM-laden viscose fibers. Thicker fibers carry a greater amount of phase change material. “The performance compared to a standard PCM viscose fibre here is four times higher,” says Martin Bentz, managing director of Outlast Europe.
