The Ryon Phuket uses elements based on the phenomenon of "Pelitier" to transfer heat electrically to cool or warm the human body according to the Sony website (here).
Wearing the shirt and placing the device with a special pocket in it covers the neck area from the back, and pushes the cold air..
Instead of sending a cold breeze, the cold part works on the surface of the body to cool it directly, so that you can use it even if you wear a shirt and a robe over it..
Upon experimenting with the "Rion Phuket" device at 30 ° C in the event of rest, the body surface temperature decreased 13 ° C at the contact point, after 5 minutes.
By taking advantage of the Belitier mechanism, in contrast to the delivery of heat, it can also warm the human body in the winter.
The device is equipped with wireless connection via Bluetooth technology, and it uses an application on the smartphone to control the heat, as it provides 4 degrees to switch between cold and hot and adjust the effect.
