An apparatus and a method for activation of at least one element. The apparatus comprises at least one activation layer and at least one migration layer arranged at the at least one activation layer and being permeable to a fluid along a transversal direction across a surface of the at least one migration layer, such that a change of doping level in the at least one activation layer is achieved, for activating the at least one activation layer along the transversal direction, wherein a substrate onto which the activation layer and the migration layer are deposited comprises an opening being sealed by a gas permeable membrane, the gas-permeable membrane being in contact with a fluid container.
