Outline of Final Research Achievements

We have been developing the measurement technique of the amount of generated acoustic cavitation. The conventional cavitation sensor was not able to accurately measure the generation distribution of acoustic cavitation in standing wave acoustic filed. Therefore, the new cavitation sensor was developed with the aim of high spatial resolution. The sensor was reduced the size of PVDF. As the result, the spatial resolution of the new sensor was improved than the conventional sensor. Also, the new sensor had the potential to be able to accurately measure the generation distribution of acoustic cavitation in the standing wave acoustic filed.
