Wearable Air Conditioners

Miniature, wearable air conditioners will come to market for the rest of us.

For many years, Japanese and Chinese workers who must wear protective suits during summer’s intense heat have used wearable fans to keep cool. These tiny fans generate air inside their suits, while ventilation flaps let body heat escape.

Now, miniature, wearable air conditioners will come to market for the rest of us. Sony developed the Reon Pocket, which relies on a phenomenon known as the Peltier effect, which moves heat between objects using electrical currents.

In place of a servomotor and fan, this flat device is embedded into a shirt. Your mobile phone controls the thermostat and the wearable Reon Pocket can cool or heat your body by 23 degrees or 14 degrees Fahrenheit, respectively.
