High-tech heating patch: a way to save energy and keep warm

Yesterday, a strong wind visited Beijing again, the temperature turned sharply, and some netizens shouted in the cold wind. Indeed, in the cold winter days, how to resist the cold is a topic of great concern to people. Scientists at Rutgers University and Oregon State University have recently come up with a cost-effective way to help people stay warm.

They used a strong light pulse to fuse the tiny silver wire with the polyester to create a thin and durable heating patch. According to Rutgers University's scientific report, their heating performance is nearly 70% higher than similar patches created by other researchers. Moreover, they are inexpensive, can be powered by button batteries, and can be sewn into clothes as a patch to generate heat where the body needs it.

According to research, 47% of the world's energy is used for indoor heating, and 42% of energy is wasted to heat space and objects instead of directly heating the human body. If you want to solve the global energy crisis and control global warming, you need to significantly reduce the energy of indoor heating.

Related researchers also said that it was previously a waste of energy by heating the building, rather than selectively heating the human body. Personal thermal management, focusing on heating the body as needed, is an emerging potential solution. The application of the heated patch will be very important.

Each patch created by Rutgers and Oregon produces more heat than the current state of the art, and is more durable after being bent, cleaned, exposed to high temperatures and high humidity. At the same time, engineers will also study the location and comfort of their applications in clothing. Such heated patches can also help people who work outdoors for a long time, such as duty personnel, outdoor cleaners, and the like.

The study was published in the journal Science Report.
