Freezemat is a brilliant material for dynamic cooling cycle, uses a bionic intelligent polymer, a temperature-sensitive hydrogel, to mimic the cooling mechanism of a living organism: dissipating heat by evaporation. Once the ambient temperature hit the threshold of the evaporation point of hydrogel, the water molecules evaporate and carries the heat away; when the temperature come back under the threshold, the Freezemat replenishes water particles from the environment. This cycle will keep on looping to ensure your device is always on the right temperature.The whole cooling process is power-free and silent, effectively solves overheating problem of fanless devices. Enjoy the beauty of nature's work.
