From Stanford News:
Stanford researchers have developed a reversible fabric that, without expending effort or energy, keeps skin a comfortable temperature whatever the weather.
In a paper published Nov. 10 in Science Advances, a team led by Yi Cui, professor of materials science and engineering, created a double-sided fabric based on the same material as everyday kitchen wrap. Their fabric can either warm or cool the wearer, depending which side faces out.
This project came out of Cui’s interest in energy efficiency and his expertise in manipulating nanoscale materials. He thought if people could be more comfortable in a range of temperatures, they could save energy on air conditioning and central heating.
“Why do you need to cool and heat the whole building? Why don’t you cool and heat individual people?” asked Cui.
