It is difficult to use conventional hydrophones for measurement of high power ultrasound field with acoustic cavitation by high intensity focused ultrasound (HIFU) device or ultrasound cleaner, because a front electrode of the piezoelectric element in conventional type hydrophone was decorticated by acoustic cavitation and high sound pressure. We fabricated new toughness type hydrophones using titanium membrane acoustic receiving surface and hydrothermally synthesized lead zirconate titanate (PZT) film for measurement of high power ultrasound. We measured the acoustic field distribution (sound pressure distribution) by HIFU equipment and ultrasound cleaner. Our new type hydrophone could receive high power ultrasound without broken. |
