Description
Piezo focusing spherical cap is the core element for HIFU ultrasound transducer. The frequency of this HIFU spherical cap focused piezoelectric element is 4.0MHz. Its diameter is 19.8mm and curvature radius is 15.5mm. It is different from common PZT components. The surface is concave, so machining is much more difficult. Its electrode type is wrap-around.
Piezoelectric ceramic hemisphere has many applications. For example, we can apply it for medical and cosmetic HIFU transducers. High-intensity focused ultrasound is a kind of non-invasive treatments. Piezo focus bowls can be used for scars, skin tightening, tumours, etc.

④ Strong customization ability: multiple shapes, electrode types, sizes, and thicknesses to choose from. And we can customize the circuit driver board.
⑤ Wide applications: suitable for ultrasonic beauty, ultrasound lipolysis, physical therapy, fetal aspiration, etc.
Precautions for using piezoelectric ceramic sphere focus bowls:
① Piezo focus bowls should be firmly combined with metal parts. The bonding temperature should not exceed 120 ℃.
② When welding wires, the speed should be as fast as possible. Otherwise, high temperature will affect the polarization of piezoelectric ceramics.
③ PZT ceramic sphere is fragile product. Strong vibrations or impacts may cause damage. So please assemble carefully.
④ During the use, please don’t prolonged dry burning. It’s to avoid performance degradation of piezo focusing spherical cap.
