What is pressure power generation what is said to be a crystal 5

I've also heard of this thing, which is a semiconductor that is being perfected. I don't know exactly what it is, but I can use the difference in atmospheric pressure to generate electricity.

The piezoelectric effect of crystals refers to the phenomenon that some crystals will produce an uneven distribution of charges under the action of force, and then produce a potential difference on their surface.

Extension: The crystal piezoelectric effect is a special physical effect, and its application involves many fields. In electronic engineering, piezoelectric materials are widely used in sensors, actuators, control systems, vibration motors, radio equipment, and other fields.

In the biomedical field, piezoelectric crystals can also be used to make imaging instruments, ultrasound** equipment, and ultrasound locators. In addition, the crystal piezoelectric effect has an important application – underwater communication.

Due to the large dielectric constant of water, the loss and attenuation of underwater communication signal transmission are very serious. However, piezoelectric crystals have excellent mechanical vibration and acoustic properties, making them ideal for underwater detection and communication. The transmission and reception performance of piezoelectric crystals can achieve high quality and high reliability of underwater communication, and can be widely used in marine resource exploration, underwater exploration, seabed topographic mapping and other fields.

In addition, piezoelectric crystals can be used as a stable clock source in the manufacturing process of electronic devices. Because the vibration frequency of piezoelectric crystals is relatively stable and highly controllable, and is less affected by environmental factors such as temperature and humidity, they can be used to make high-precision, low-bias clock sources, such as quartz crystal oscillators.

In short, due to the wide application prospects and excellent performance of crystal or standby piezoelectric effect, it has become one of the indispensable and important components in the development of modern science and technology. In the future, with the continuous advancement of scientific and technological progress, the application of code back voltage transistors in more fields will become more and more extensive.

Non-centrally symmetrical crystals, under the action of mechanical force, produce deformation, so that the charged particles are relatively displaced, so that positive and negative binding charges appear on the surface of the crystal, such crystals are called piezoelectric crystals. The property of the potential difference between the two ends of the polar axis of the piezoelectric crystal is called piezoelectricity, and the cause of piezoelectricity is related to the crystal structure. The center of gravity of the positive and negative charges that originally coincided was compressed and separated to form an electric dipole, so that the two ends of the crystal in a specific direction have different symbolic amounts of charge.

2] The common feature of null piezoelectric crystals: the crystal point group (symmetrical type) does not have a symmetrical center. Among the 32 point groups of the crystal, 21 point groups do not have symmetry centers, but the crystals of point group 432 do not show piezoelectricity, so the crystals of 20 point groups are piezoelectric.

Thank you for the trouble to adopt!
