1. Quartz crystal and piezoelectric ceramic, are these two the same in piezoelectric effect?
Quartz crystals and piezoelectric ceramics, the piezoelectric effect of these two piezoelectric plate crystal, from a professional point of view, is not the same. Because there is no volumetric deformation piezoelectric effect in quartz crystals, but in piezoelectric ceramics, Therefore, the above conclusions will be reached, and this is the main difference between them.
2. If the piezoelectric ceramic is always pressed, will there always be the current ?
In the case of piezoelectric ceramic strips manufacturer PIEZOHANNAS, the answer is no, because piezoelectric ceramics generate current because of the positive and negative charges on the surface, which leads to the generation of voltage, and then Producing current. If the potentials of the two surfaces are equal, then the current will stop and there will be no discharge process. Therefore, it has been pressed and there is no current.
3. What are the similarities between power generation fibers and piezoelectric ceramics?
About both materials, if they are in contact, electricity is generated under certain conditions, so that electrons can be transferred. However, when the materials are separated, the material of piezoelectric ceramic transducer that receives the electrons becomes a negative charge. At this time, if the connection is made through a loop, then a current-balanced charge is generated, but it is not very large.
