The idea and successful practice of a stress sensor to sense mechanical by an artificial skin, i.e., self-diagnosis thin film, has been realized, through the fabrication high-luminescence piezoelectric film which can reproducibly emit strong visible light upon stressing. strongest luminescent consists nanosized crystallites ZnS doped with 1.5 at. % Mn, in Mn acts as emitting center. intensity emitted luminescence responds applied directly onto or underlying material reversibly reproducibly, so it be used skin stress.
