Abstract
A method for manufacturing a pressure sensor having a pressure-sensitive medium. The method includes: providing a pressure sensor having a pressure sensor element, which is arranged in a receiving space of a housing of the pressure sensor; filling the receiving space with a pressure-sensitive medium; applying a second medium, which is immiscible with the pressure-sensitive medium, to a surface of the pressure-sensitive medium; forming a membrane in a boundary region between the pressure-sensitive medium and the second medium by way of a phase-transfer reaction between a first reactant and a second reactant, at least the first reactant or the second reactant being dissolved in the pressure-sensitive medium or in the second medium. A pressure sensor manufactured by the method is also described.
