The paper describes design of new patented Acoustic Emission Friction Brush Probe for solid surface characterization. During constant speed brush movement over the analyzed surface, the brush Jibers in contact with surface generate acoustic emission (AE) signal, AE signal is evaluated using DSP based AE analyzer DAKEL-XEDO, Simultaneously with AE, the integrated probe measures the normal and tangential forces acting on brush. Probe has been tested on etalons of surface roughness, The probe has been developed in the frame of common Czech - French collaboration program BARRANDE for a human skin characterization in dermatology, but other technical applications in material science are mentioned. Designed probe represents simple and cheap alternative to the atomic force microscope (AFM),
