Abstract: The field of the DISCLOSURE lies in adaptive materials for implementation in textiles, wearables and smart clothing. The present disclosure relates to functional fabrics or devices, comprising fabrics or fiber-based materials with selective reversible permeability or which reversibly change permeability upon stimulation with at least one external stimulus selected from humidity, temperature, electrical, magnetic, pH, and chemicals. The present disclosure also relates to the use of said functional fabrics or devices, in particular as humidity sensors, temperature sensors, for humidity and/or heat management of clothing or of textiles for home, as well as for outside purposes. The present disclosure also relates to wearable electronics, smart thermo-regulating clothing or textiles and Nsport bandages. The present disclosure also relates to devices comprising a sheet-like substrate and temperature responsive materials N applied thereon, respective printed actuators and their uses as shape changing interfaces.
