Method of determining at least one dynamic characteristic of a sample of a deformable solid or fluid material, comprising: the contacting of said sample ( 24, 42 ) with at least one interaction surface ( 23, 25, 41 a , 41 b); the application of a relative movement between said sample ( 24, 42 ) and said interaction surface ( 23, 25, 41 a , 41 b); and the measurement ( 26 ) of at least one dynamic or kinematic quantity in respect of the sample ( 24, 42 ) and/or said interaction surface ( 23, 25, 41 a , 41 b), wherein said interaction surface ( 23, 25, 41 a , 41 b) has an intrinsic wettability with respect to the material that is higher than that of metals. Device for implementing this method. According to particular embodiments, said interaction surface ( 23, 25 ) is made of high-density sintered ceramic or made of single crystal silicon or germanium, preferably having a zero open porosity and an arithmetic mean roughness parameter of less than 12.5 mum and preferably between 0.4 and 1.6 mum.
