Nanowire-Based Personal Cooling Unit

Apr-29-16 A personal cooling unit based on nanowire technology could offer a new level of protection for people subjected to high temperatures, such as firefighters and athletes.

The material is an improvement on previous versions of what is called electrocaloric ceramic materials, which will cool when subjected to an electric current. Whereas past materials were either too rigid, or required dangerous levels of electricity to function, the nanowire-based material can cool about 5.5°F using only 36 volts, which is safe for people.

The material could one day find its way into clothing, as a substitute for the ozone depleting large-area cooling systems in use today.
