Piezoelectric ceramics function and beauty device drive circuit

Piezoelectric ceramics are a kind of information function ceramic material that can convert mechanical energy and electrical energy into each other - piezoelectric effect, piezoelectric ceramics in addition to piezoelectricity, but also have dielectric, elasticity, etc., has been widely used in beauty skin care, medical imaging, sound sensors, sound transducers, ultrasonic motors, etc. Piezoelectric ceramics use its material under the action of mechanical stress, causing the internal positive and negative charge center relative displacement and polarization, resulting in opposite symbols of binding charge on the surface of both ends of the material, that is, piezoelectric effect and production, with sensitive characteristics, it is more in daily life for people, for people to create a better life and efforts.
Beauty device is a machine that adjusts and improves the body and face according to the physiological functions of the human body, it has whitening, skin rejuvenation, freckle removal, wrinkle removal, hair removal, weight loss, etc. according to the name, according to the name, ultrasonic introduction, photorejuvenation, RF radio wave peeling, electronic spot removal nevi, etc. The ultrasonic head in the massager uses the principle of ultrasonic transducer to achieve vibration. It is mainly composed of a transducer and a metal head, of which the transducer is an oscillating device, which oscillates at high speed at a frequency of 1MHZ when working, and the energy generated is transferred to the surface of the metal head by the metal head to vibrate. Transducer tablets play a great role in the massager, which can use the principle of shock to massage skin cells, improve cell metabolism, enhance cell vitality, improve skin tissue nutrition, and make the skin rosy. More resilient.
