Materials scientists at the USA’s Duke University have developed a lightweight material that traps thermal energy when dry but opens a series of tiny vents to let heat escape when a person starts sweating. The vents close again to retain heat once they are dry.
Using physics rather than electronics to open the vents, the material has potential as a patch on various types of clothing to help keep the wearer comfortable in a wide range of situations.
