Abstract (en)
[origin: WO2021144349A1] The invention relates to a self-learning device for measuring pressure, gas and/or humidity, and to a method for measuring pressure, gas and/or humidity. The device comprises at least one sensor for measuring pressure, gas and/or humidity, wherein the sensor comprises at least one capacitor with at least two electrodes which are arranged relative to each other 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 humidity-permeable and/or humidity-absorbing and/or gas-permeable and/or gas-absorbing humidity 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 humidity layer. In this way, a capacitance changes at least partially as a result of at least some of the humidity coming into contact with the dielectric layer, a processing unit being configured and intended for measuring and/or storing this change, so that a capacitive humidity sensor is created.
