Abstract
The system has polymeric hydrogel (4) provided as sorbent. Water discharge of the hydrogel is switched by a change in ambient temperature after reaching and exceeding a temperature shift of the hydrogel in a condensed form, where the temperature shift lies at 25 to 35 degree Celsius. A working stroke of the hydrogel lies between 15 and 50. The hydrogel is immobilized on and/or in a carrier substrate. A textile material (5) or a non-woven fabric or a structured metallic, polymeric or ceramic surface is provided as the carrier substrate. Independent claims are also included for the following: (1) a composite for drinking water extraction by absorption of atmospheric moisture from an environment using a sorbent (2) a method for drinking water extraction by absorption of atmospheric moisture from an environment using a sorbent.
