Abstract (en)
[origin: EP4173506A1] The present invention relates to a pod (1) including a light-switchable layer (7) for an aerosol-generating device in which leakage of an aerosol-generating liquid material (e-liquid) during transit and storage is prevented. This is achieved by a pod (1) for an aerosol-generating device comprising a porous wick (2); a reservoir (3) including a discharge opening (4) for an aerosol-generating liquid material; and at least one light emitting source (6), wherein the porous wick (2) is coated with a light-switchable layer (7) on a surface thereof sealing the discharge opening (4) of the reservoir (3) so that the light-switchable layer (7) is arranged between the discharge opening (4) of the reservoir (3) and the porous wick (2), wherein the light-switchable layer (7) comprises an amphiphilic inorganic material being hydrophobic and impermeable for an aerosol-generating liquid material in the dark and becoming hydrophilic and permeable for an aerosol-generating liquid material when exposed to light, and wherein the at least one light emitting source (6) is configured to illuminate the light-switchable layer (7). Furthermore, the present invention also relates to an an aerosol-generating device comprising the pod (1).
