摘要

对超声振动估计皮肤表面海绵性时扫描信号工作频率的选择进行了研究。设计了实验装置。结果表明，在与空气接触和与皮肤表面接触两种情况下，压电板电压的最大变化都发生在谐振频率处。所考虑的散热器的最佳扫描信号频率为485 kHz。

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

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.
