Acoustic radiation force (ARF) was applied to the object with 1 MHz ultrasound applicator and the small displacement was measured by phase tracking method of 120 MHz ultrasound. The viscoelastic properties were obtained by analyzing the temporal response of the object to ARF. The efficacy of the method was validated by the measurement of artificial skin with three-layered structure. The method may contribute to smart-ageing evaluation of skin.

用1MHz超声源对被测物体施加声辐射力，用120MHz超声相位跟踪法测量微小位移。通过分析物体对ARF的时间响应，得到了物体的粘弹特性。通过对三层结构人工皮肤的测量，验证了该方法的有效性。该方法可有助于皮肤的智能老化评估。
