A transdermal device () comprising at least one substrate () arranged to be applied against the dermal surface or the mucous membrane. The at least one active ingredient is grafted to the substrate () by at least one photolabile ligand, and at least one light source () operated by a control mechanism arranged to generate light pulses, of a predetermined wavelength, intended to break covalent bonds between the active ingredient and the ligand in order to release the active ingredient from the substrate (). The substrate () comprises at least one porous matrix () with a three-dimensional structure comprising a plurality of pits () organized in a sponge-like fashion and constructed of a polymer chosen between chitin and chitosan, and the matrix () defines at least one three-dimensional tank (). The active ingredient is contained and grafted by the ligand.
