| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have been developing and evaluating tough hydrophones using titanium front plate, titanium backing and a hydrothermally synthesized PZT polycrystalline film to measure high-intensity ultrasound fields with the occurring of acoustic cavitation. We confirmed that the receiving sensitivity of the hydrophone does not decrease even after being exposed to an ultrasound cleaner for a cumulative total of 100 hours. However, it was necessary to examine the durability in the focused ultrasound field such as HIFU. Therefore, the tough hydrophone was exposed to a focused ultrasonic irradiation system using a concave piezo electric transducer, and the durability was evaluated. It was confirmed that the frequency characteristics of the receiving sensitivity of the hydrophone did not decrease even after exposure for a total of 30 hours. | |
