Crystals - Application Field and Working Principle

Crystals, also known as piezoelectric crystals or oscillators, are a type of electrical component that can be used for a variety of applications. Crystals are used in a variety of industries from consumer electronics to medical devices. Crystals can be used to generate accurate frequencies, to detect waves and signals, or as a timing device for events such as in watches, computers and radio transmitter. The crystal is a quartz crystal, usually called oscillator, usually with a frequency range between 4,000 and 60,000 times per second. Crystals can also be used in the production of crystal oscillators and quartz filters.

Application of Crystals

Crystals are used in many different areas, ranging from consumer electronics, to military applications, and even medicine. In consumer electronics, crystals are used as a timing device in devices such as radios, televisions, and computers. They are also used as a signal receiver for GPS or cellular phones. In the automotive industry, crystals are used in car radios and navigation systems. In the medical field, crystals are used for imaging and diagnostic purposes, as well as for hearing aids. Crystals are even used in military applications, such as for navigation, targeting, and surveillance. Crystals can also be used as a reference for frequency standards, as well as for frequency control.

Types of Crystals

Crystals come in a variety of types and sizes. Some of the most common types of crystals include quartz crystals, dielectric crystals, ceramic crystals, and SiC (Silicon Carbide) crystals. Quartz crystals are used in the production of oscillators, crystal filters, and resonators. Dielectric crystals are used as capacitors and in the production of microcircuitry. Ceramic crystals are used in the production of oscillators and filters, as well as for surface acoustic wave (SAW) devices. SiC (Silicon Carbide) crystals are used in the manufacture of ultra-wide band devices, as well as in filters, oscillators, and resonators.

Working Principle of Crystals

The working principle of crystals is based on the piezoelectric effect. Piezoelectricity is the production of an electric voltage in certain materials due to physical pressure. This effect occurs when an electrical charge is applied to a material, such as a crystal. The pressure causes the material to vibrate, leading to a voltage being created. This voltage can then be used for a variety of purposes, such as for timing signals, frequency control, and other uses.

Conclusion

Crystals are an important electrical component in a variety of industries, and can be used for a variety of applications. They are used in consumer electronics, automotive, medical, and military applications, as well as for the production of crystal oscillators and quartz filters. The working principle of crystals is based on the piezoelectric effect, where an electric voltage is created due to physical pressure on the material. Crystals can be used for timing signals, frequency control, and other purposes.
