Application of HIFU Piezo Ceramic:

Ultrasonic focus ceramic (HIFU) is widely used in the beauty, weight loss medical industry and liposonix,ultra Shape.On behalf of the product is this year the rise of the ultrasonic knife, Liposonix slimming Instrument,Ultra Shape slimming instrument. Compared to the traditional laser beauty weight loss products, the advantages is non-invasive, safe, effective for a long time.

High Intensity Focused Ultrasound(HIFU)：

High Intensity Focused Ultrasound is a non-surgical, no downtime, in-office procedure for lifting and tightening sagging skin of the brows, cheeks, lower face (jowls), jawline and neck. Ultrasound technology is focused below the skin surface to firm and lift droopy tissues. Results are long lasting and occur gradually but dramatically over time.

How does HIFU work?

It utilises ultrasonic energy to penetrate deep below the skin and fat layer of the face to gently but effectively target connective tissue. Connective tissue is a firm, tough layer that supports the neck and facial contours. Ageing and the passage of time cause connective tissues to droop. High Intensity Focused Ultrasound tightens loose connective tissue, creating firmness and lifting to areas of sagging skin. The layer of tissue targeted is the same tissue that plastic surgeon’s tighten and shift during a surgical facelift or brow lift.

Standard Size of HIFU Piezo Ceramic:

Working Frequency : 1 ~ 10 MHz (Selectable)

Aperture size : Diameter 20 ~ 70mm(Selectable)

Focal length: 10 ~ 100 mm (Selelctable)

Strong Electrode: Silvering ,Nickel, Titanium Alloys
Long Lifetime: high power pulses>15000

PZT Material:

 

- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.

- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.

- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
