Choice of scanning signal working frequency for skin surface sponginess estimation using ultrasonic vibrations

Abstract

The research on the choice of scanning signal working frequency for skin surface sponginess estimation using ultrasonic vibrations has been made. The experimental setup has been designed. It is shown that the maximum change of the piezoplate voltage is at the resonance frequency for both cases: contact with air and contact with skin surface. The optimum scanning signal frequency for the considered radiator is 485 kHz.
