Application: ultrasonic beauty shovel

Ultrasonic Vibration transducer for cosmetic spade

It provides a new method of health care and skin care for people. It adopts physical therapy and carries out safe and effective health care according to the characteristics of human skin. The shovel head vibrates 25,000 times per second to decompose and derive the dregs and dead skin in the pore. Regular use can shrink pore, tighten skin, fade spots, smooth wrinkles, so that your skin restores health and elasticity, bloom youth and luster. Using low voltage power supply, it is safer and has longer service life.

Material: PBaS-4 (hard PZT)

PBaS-4 is a modified hard PZT dedicated for extremely high power high driving etc. transducers with higher power handling capability than PZT-4 series.
