The invention relates to a device for measuring pressure and/or moisture, and to a method for measuring pressure and/or moisture. The device comprises at least one sensor for measuring pressure and/or moisture, the sensor comprising at least one capacitor with at least two electrodes, which are arranged in particular in a horizontal direction along and on an in particular flexible substrate material. At least one dielectric layer is arranged between the electrodes. The invention is characterized in that at least one at least partially liquid-permeable and/or liquid-absorbing moisture layer is arranged in at least some locations on a side of at least one electrode and/or the dielectric layer facing away from a substrate material. In a transverse direction, the at least one electrode and/or the dielectric layer is/are thus arranged between the substrate material and the moisture layer. In this way, a capacitance changes at least partially as a result of the liquid coming into contact with at least some of the dielectric layer, a processing unit being configured and provided for measuring and/or storing this change, so that a capacitive moisture sensor is created.
