20 Wonderful Piezo Crystals. Number 16 is Absolutely Stunning

Piezoelectric ceramic as a transformer based on the application of principle. Piezoelectric ceramic transformers are solid state electronic transformers that work in audio or super audio. Compared with the traditional core wire of piezoelectric cylinder transducers wound electromagnetic transformer, the utility model has the advantages of small volume, light weight, not breakdown when it is used, there is high temperature resistance of the transformer itself, no fear of burning, no electromagnetic interference, simple structure, simple manufacturing process and mass production . Piezoelectric transformers are mainly used in drives, + (, + ((DC, DC) transformers, in addition, the piezoelectric transducer tubes for piezoelectric transformer is also used in the military, that is, they use its output electrode tip discharge detonating high-pressure detonator. Such as neon drivers, high-voltage anti-theft devices, high voltage electric shock sticks, small-light machines, radar, photocopiers, helium, neon and small carbon dioxide-based phosgene, etc. Piezoelectric ceramic transformers are formed by different components.The crystal structure of the pole symmetric point group is realized by using the inverse piezoelectric effect and the positive piezoelectric effect, and the piezoelectric effect of ultrasonic air transducer is illustrated by the piezoelectric effect. When a compressive stress parallel to the polarization direction is applied, the pezo ceramics piezoelectric sensor crystal body undergoes compressive deformation, moment is smaller, the polarization intensity is binding charge density becomes smaller, leaving the electrode surface appear free of charge generated by the phenomenon of free charge.such as piezoelectric sensor hydrophone is applied along the polarization direction of the tensile stress, then the phenomenon of charging, which is the positive piezoelectric effect .When an electric field of the same polarity as (or opposite to) the polarization direction is applied to the piezoelectric ceramic body, since the direction of the electric field is the same as (or opposite to) the direction of polarization, it acts to increase (or decrease) the polarization strength so that piezoelectric ceramic body caused by growth (or shortening) along the polarization direction to produce strain and stress, the stress and strain of piezoelectric transducer materials can be applied to the external objects or propagation medium, which is the inverse piezoelectric effect. No matter what the shape of the piezoelectric bimorph tube for piezoelectric transformer is the positive and negative piezoelectric effect of the piezoelectric vibrator organic combination of the inverse piezoelectric effect as an input end, the positive piezoelectric effect is as the output part of the horizontal and vertical type piezoelectric transformer structure as shown. The second conversion of the electromechanical energy of the piezoelectric ceramic, the mechanical energy and the electrical energy can obtain the highest output voltage at the resonant frequency of the transformer due to the different impedances of the input part and the output part in the process of energy conversion and transmission.The voltage output is to achieve the effect of transformation.
