A new easily-applicable method for immediate evaluation of human skin local anisotropy is described in this paper. Results are of great interest in dermatology, plastic surgery, and cosmetics. The method is also utilizable in many industrial applications for anisotropy evaluation of various materials like composites, etc. Proposed system exploits a special flexible multi-directional circular probe with built-in piezoelectric elements for elastic waves propagation measurement, and the anisotropy level of the tested structure is determined from directional dependence of elastic wave velocity. The method was tested on human skin tissue in-vivo and on samples of CFRP.
