Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.

Abstract: A sealing assembly includes: a first machine element and a second machine element, which delimit a gap; and a sealing element arranged in the gap, the sealing element sealingly laying against the second machine element under an elastic bias, the sealing element having a first section and a second section, the first section coming into contact with a medium to be sealed off. The sealing element includes at least one sensor, the at least one sensor detecting a contact pressure exerted by the sealing element. The at least one sensor is associated with the second section.
