9B11000185 application field and working principle

Crystals, derived from the Greek word "krystallos" meaning icy cold, play a very important role in modern electronics. Crystals are the basic building block of quartz-based electronic components and are used in a wide range of electronic applications. Crystals come in many shapes, sizes, and frequencies and are used in a variety of applications, such as timing devices, oscillators, amplifiers, filters, and antennas.

The specific application of a crystal depends largely on the properties of the crystal, including the frequency. The frequency of a crystal is a measure of how often it vibrates or oscillates. Different materials will vibrate at different frequencies and so, by selecting the proper materials, it is possible to design a crystal to vibrate at almost any frequency.

Crystals can be divided into two main categories: piezoelectric and thermal. Piezoelectric crystals have the ability to convert electrical energy into mechanical vibrations and are commonly used in timing devices, oscillators, and filters. These crystals are also able to generate electrical energy from mechanical vibrations, which makes them ideal for use in micro-electro-mechanical systems (MEMS) for various industrial and consumer applications.

Thermal crystals, on the other hand, are made of materials that contract or expand in response to temperature changes. Thermal crystals are often used to measure temperature or in temperature sensors. They are also used as reference crystals in frequency control applications or as structural materials, owing to their mechanical strength.

The working principle of a crystal relies on the fact that a vibrating crystal emits electrical currents. This is because the vibration of the crystal causes electrons to move back and forth along its surface at high speeds. When the signal frequency of the power source matches the resonance frequency of the crystal, the moving electrons create an electrical signal.

The resulting signal must then be amplified before it can be used in any application. This amplification is typically done using a circuit and components such as transistors, diodes, and capacitors. The frequency of the signal can also be changed using different types of capacitors and inductors in order to produce a signal at a different frequency.

Crystals are essential components in a variety of electronic applications and are used in everything from watches and computers to mobile phones and televisions. They provide the necessary oscillations and signals for accurate timing and reliable electronics.
