Abstract

Surface acoustic wave (SAW) shows advantages in revealing skin mechanical properties. In this paper, we evaluates the elasticity of tissue mimicking phantoms by inversion of SAWs phase velocity to Young's Modulus, the estimated SAWs evaluating depth is determined based on the assumption of that SAWs penetration approximately equals one wavelength. The tissue mimicking phantoms are made of agar with concentration of 1%, 2% and 3%. Their elasticity tested from our system is 13.3 kPa, 53.4 kPa and 257.9 kPa respectively, with expected gradient. The evaluation depth is then estimated as 0.542 mm to 3.403 mm underneath the phantom surface, which indicates that this method is suitable to measure elasticity in dermis layer of skin.
