What is the definition of HBM sensors? What is classification?

The HBM sensor is a device for obtaining information, and its definition can be divided into two categories: broad and narrow. The broadly defined sensor refers to a device that can sense external information and convert it into information that is easy to measure and control according to certain laws; Narrowly defined sensors refer to devices that only convert external information into electricity according to a certain pattern.

The information obtained by sensors can be various physical quantities, chemical quantities, and biomass, and the converted information can also come in various forms. From a development perspective, the measurement and control of some information may not necessarily require electricity consumption, but other forms such as light may be more convenient. At present, most sensors still convert external information into electricity, as it is easier to match with the more mature electronic information technology and computer technology, in line with the principle of convenient use.

Previously, sensors were referred to as& Ldquo; Sensitive components; Rdquo& Amp; Ldquo; Sensing element; Rdquo; Wait, it has now been clearly stated& Ldquo; Sensitive components; Rdquo; It is a part of the sensor and cannot replace the term 'sensor'. The conversion part that makes up the sensor has always been referred to as& Ldquo; Conversion Components; Rdquo;, Considering the continuous development of technology, this part can have more functions besides conversion functions, so it is more appropriate to call it pretreatment unit, and this definition is more progressiveness. For English; Ldquo; Transducer& Rdquo; And& Ldquo; Sensor& Rdquo; Both words should be translated as& in Chinese; Ldquo; Sensors& Rdquo.

There are also broad and narrow categories of sensor technology. Broadly speaking, it includes both the manufacturing and testing technology of the HBM sensor itself, as well as the relevant technologies and application technologies required for the production of sensors. Narrowly speaking, it only includes the manufacturing and testing technology of the sensor itself.

Sensor technology belongs to the high-tech category and is also a new type of technology, involving relatively new and challenging technical fields. In order to facilitate the development of sensor technology, China defines the scope of sensor technology from a broad perspective.

There are various types of sensors, covering a wide range of fields, almost including all modern disciplines, and there are also many classification methods. According to the principle of HBM sensor transformation, it can be divided into capacitive sensors, inductive sensors, piezoelectric sensors, etc; According to HBM sensor technology, there are two main categories: structural sensors and new sensors. Structural sensors are advanced technologies developed in the 1960s that detect the deformation or displacement of a structure (such as a metal diaphragm). But with the development of technology and the continuous emergence of new sensors, structured sensors are facing new challenges and will gradually be phased out. New sensors refer to sensors made of semiconductors, ceramics, optical fibers, and other new materials that have emerged in recent years, compared to traditional structured sensors. Sometimes referred to as a physical property sensor.

The basic characteristics of a new type of sensor are inseparable from the performance of the core materials that make up its sensitive components, which utilize the inherent characteristics of the materials to detect external information. For example, a photosensitive sensor can be made by changing the properties of a material under illumination; Magnetic sensors can be made by changing the characteristics of materials under the action of a magnetic field. The phenomenon of a material changing its properties under external conditions is usually described as various effects. In theory, various effects may serve as the fundamental effects of sensors. Due to the direct utilization of various effects of materials, various conversion processes are saved, and the combination of sensitive and conversion components is beneficial for achieving the solidification of HBM sensors, reducing volume, eliminating movable parts, and improving reliability. New sensors are often produced using microelectronic technology, which is easy to mass produce, has good consistency, and has low production costs.

Sensors are usually divided into three categories based on their external information and transformation effects, namely HBM sensors, physical sensors, chemical sensors, and biosensors.

Physical sensors utilize physical effects to process physical quantities such as light, sound, and magnetism, which were developed earlier and therefore more mature. Among them, electrons play a conductive role and are relatively easy to develop.

Chemical sensors mainly use chemical effects to detect the types and concentrations of chemical substances. Among them, ions play a conductive role. There are many types of ions, so chemical sensors vary greatly and are more complex, making their development relatively difficult.

Biosensors are sensors that utilize the selective ability of bioactive substances, such as molecules, cells, and even certain biological tissues, to certain material characteristics, such as glucose sensors formed by the combination of glucose and microelectrodes. The research history of biosensors is relatively short, but their development is very rapid. With the development of semiconductor technology, microelectronics technology, and biotechnology, their performance will be further improved, and multifunctional, integrated, and intelligent biosensors will also become a reality, with a very promising future.
