Could a ‘smart sweater’ lower your heating bills?


A group of researchers at Stanford University recently published a study on the use of nanowire-coated fabric to help the body conserve thermal energy. The fabric can trap heat inside a person’s clothes, making it unnecessary to heat empty rooms in order to keep the people within them warm.

The breathable nanowire fabric is coated in silver nanowire fibers and works by reflecting the infrared radiation that humans naturally emit back into the body. Garments made from the nanowire fabric could also utilize active heating to warm wearers.

Clothing made of the material could save the average person $200 per year on heating, the study’s lead scientist Yi Cui told Popular Science. Indoor heat is a massive global expense; the International Energy Agency reported that almost half of the total global energy use goes heating, primarily in residential buildings.  READ MORE.
