Conductance Changes, Electric and Electrokinetic Effects

The propagation of an ultrasonic wave and cavitation can produce several electrical effects which include  

Electric [152] and electrokinetic effects in solution and at liquid-diquid or solid-diquid interfaces (Debye effect [153], U-effect [154]). 

Although these effects are related to ultrasound intensity, to date there have been no attempts to derive quantitative correlations. These effects could be useful to get

Class 4-Methods Based on Secondary Effects of Sound Propagation and Cavitation. These include methods based on volume changes [142-144], acoustic output and noise measurements [145—150], conductance changes, electric and electrokinetic effects [151-156], sonoluminescence [157-171], and chemical probes [172-198].
