the advantages is non-invasive, safe, effective for a long time.
Principle of Hifu application:
The principle is a combination of physical combination of collagen repair nutrition, two-pronged beauty, through the RF probe to produce ultrasound on the subcutaneous tissue burning,
Damage the subcutaneous tissue, make it self-repair, regenerate new repair nutrition during the repair process, these nutrients are mainly collagen and hyaluronic acid.

3.PZT Material
We usually provide P-41,P-42,P-43,P-51,P-52,P-53,P-81,P-82,P-83,PSnN-5,
PMgN-51,PZT-5H,PZT-5X,PCrN-4,PliS-51,PbaS-4,PbaS-5,BaTio3..
PZT materials are categorized as functional ceramics. In sensors they make it possible toconvert forces,
pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers
and actuators they convert electric voltages into vibrations or deformations.Piezoelectric materials
are classified according to their chemical composition on the one hand, and by the specific
application conditions on the other.
PZT ceramic is used in a wide variety of applications. Soft (sensor) PZT ceramic powders are typically used
when high coupling and/or high charge sensitivity are important, such as in flow or level sensors;
ultrasonic nondestructive testing/evaluation (NDT/NDE) applications; or for accurate inspections of automotive,
structural or aerospace products. Material characteristics include a high dielectric constant; high coupling;
high charge sensitivity; high density with a fine grain structure; a high Curie point; and a clean, noise-free
frequency response.
Hard (high power) PZT ceramic powders are used when high power characteristics are required,
including applications such as the generation of ultrasonic or high-voltage energy in ultrasonic cleaners,
sonar devices, etc. Important powder characteristics include a high piezoelectric charge constant (d33); a
higher mechanical quality factor that reduces mechanical loss and enables a lower operating temperature; a
low dissipation factor that ensures cooler, more economical operation; high dielectric stability; and low
mechanical loss under demanding conditions.
