| Research Abstract |
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.
