Equipment for analyzing skin, comprises a vibrator able to transmit a shearing wave to the skin and an ultrasound probe which detects skin displacements induced by the shearing waves

摘要

An ultrasonic vibrator (4) uses an electrical winding (11) and armature (12) to apply ultrasonic shearing waves to the surface (S) of human skin (T) via rods (13) and a gelatin coupling medium (23). An ultrasonic probe (5) detects induced displacements in the skin caused by the shearing waves which are used to determine the Young's and shearing moduli for different skin layers and also the layer thickness An Independent claim is also included for : A method for analyzing the layers of the human skin which uses an ultrasonic vibrator emitting shearing waves and an ultrasonic probe which measures induced displacements and calculates the Young's and shearing moduli for different skin layers and also the layer thickness
