Model No.: OD19.5x 4MHz R 25 PZT-82
Piezoelectric ceramic Hemisphere
Electrode direction: thickness
Focused ultrasound does not heat the skin surface, nor does it need to pass through the skin as a medium for the transmission of laser energy, so it does not affect the tissue on the skin surface and the tissue through which the laser passes, of course, there will be no excessive heat residue on the skin surface. In this way, the epidermis will not be affected by heat, which can reduce the Eastern people's thermal reaction easily, and greatly reduce the chance of scald. Focused ultrasound therapy produces thermal coagulation points in the SMAS layer, and the thermal effect diffuses outward from the coagulation points, so the heat source is concentrated in the SMAS layer to be treated. It can produce more collagen denaturation.
Piezoelectric Ceramic Material: PZT-82
Is equal to PZT-8, hard PZT for higher mechanical quality factor, lower dielectric loss required and much higher power handling capability etc. transducers.
