Finnish scientists are working on a lightweight vest that would effectively act as an AC on the go

A group of Finnish scientists are working on a lightweight vest that would effectively act as an AC on the go, according to the Economist. A team from Finland’s VTT Technical Research Center that specializes in microfluidics — “the art of building devices that handle tiny amounts of liquid” — is currently in the process of creating a prototype of a vest that circulates chilled water. The scientists found that the material is most effective when it makes direct skin contact, so the vest will be manufactured to be clipped underneath clothing. “The electronics needed to power and control it would be shrunk into a small package contained on the back of the vest. This could be operated manually or … by a wireless link to a smartphone. Moreover, what can cool down can also, if run in reverse, warm up.”
