Abstract
The invention relates to a measuring system for measuring pressure and/or humidity, comprising at least one apparatus for measuring pressure and/or humidity, comprising at least one sensor for measuring pressure and/or humidity, wherein the sensor comprises at least one capacitor comprising at least two electrodes that are arranged, in particular, in a horizontal direction along and on an, in particular, flexible support material relative to one another. At least one dielectric layer is arranged between the electrodes. The invention is characterised in that at least one at least partially liquid-permeable and/or liquid-absorbing moisture layer is arranged at least in some places on a side, facing away from a support material, of at least one electrode and/or of the dielectric layer. The at least one electrode and/or the dielectric layer are thus then arranged between the support material and the moisture layer in a transverse direction. In this way, a capacitance is at least partially changed by the liquid at least partially hitting the dielectric layer, wherein a processing unit is designed and provided to measure and/or store measurement values of the sensor. This creates a capac…
