The present application discloses an artificial joint and a method for monitoring wear of the artificial joint. The artificial joint includes an acetabular part and a prosthetic bone part disposed within the acetabular part, and the prosthetic bone part and the acetabular part are capable of relative sliding. A dielectric layer is provided on a surface of the acetabular part facing the prosthetic bone part.
