MEMS (Microelectro Mechanical Systems)sensor overview

MEMS sensor is a multidisciplinary frontier research field developed on the basis of microelectronics technology. After more than 40 years of development, it has become one of the major scientific and technological fields that the world pays attention to. It involves a variety of disciplines and technologies such as electronics, machinery, materials, physics, chemistry, biology, and medicine, and has broad application prospects.

Today, MEMS is the most important technology for sensor miniaturization, intelligence and low power consumption! Without MEMS technology, the future of sensors will be bleak.custom piezoresistive silicon pressure sensor- Hiltech

Thomas Ortlepp, Dean of the German National Microsystem Sensor Research Institute, and Lorenz CHEN, a technical expert, visited our company to exchange and guide the MEMS smart sensors that the company is developing, and deepen cooperation.

MEMS sensors are widely used in the industrial field. MEMS sensors are required for monitoring in all aspects of industrial production, and the data is fed back to the control center, so that abnormal nodes can be intervened in time to ensure normal industrial production. It can be said that MEMS sensors enable intelligent industrial automation equipment to have perception capabilities. Various sensors are used to monitor and control various parameters in the automated production process, so that the equipment can work in a normal state or the best state, and the products can achieve the best quality. And keep staff away from production lines and equipment to ensure personal safety and health.

MEMS sensors are generally made of silicon-based materials and semiconductor integrated circuit manufacturing processes and are highly integrated sensor systems that integrate micromechanical and microelectronic functions. They are mostly used in military fields and occasions with high anti-interference environment requirements.

At present, China's MEMS industry is still in its infancy, and the main suppliers competing in the Chinese market are still multinational companies. In particular, almost 100% of mid-to-high-end sensor products are imported from abroad, and 90% of chips rely on foreign countries.

The MEMS sensor industry is an emerging industry with only more than 20 years of industrialization in the world. MEMS sensors represent the development direction of sensors in the future. They have the characteristics of small size, low power consumption and high consistency. They can be manufactured in large quantities and at low cost, which greatly broadens the application field of sensors and lays an important technical foundation for the development of smart devices. , is also an important part of the Internet of Things. At present, there are three main market segments for MEMS sensors, namely: MEMS microphone market, MSME pressure sensor market, and MEMS inertial sensor market.

Industrial MEMS sensors are devices designed according to the physical, chemical and biological characteristics and laws of materials. There are many kinds and many classification methods. The following is the editor of hiltech Sensing to sort out the types of industrial MEMS sensors for you:

Classified by use, it can be divided into pressure, displacement, speed, temperature, humidity and other sensors;

1. According to the measurement principle, it can be divided into physical sensors, chemical sensors and biological sensors. Such as voltage type, thermoelectric type, resistive type, photoelectric type, inductive type, etc.;

2. According to the relevant theory of semiconductor classification, it can be divided into solid-state sensors such as semiconductor force-sensitive, thermal, photosensitive, and gas-sensitive;

3. According to the manufacturing process classification, it can be divided into integrated sensors, thin film sensors, thick and thin sensors and ceramic sensors;

4. According to the output classification, it can be divided into analog and digital sensors. The output signal of the analog sensor is an analog quantity; the output signal of the digital sensor is a digital quantity, which is easy to use with a computer and has strong anti-interference;

5. According to the composition, it can be divided into basic sensors, combined sensors and application sensors;

6. According to the form of action, it can be divided into active sensors and passive sensors.

At the same time, the participants visited the production and test bases, and introduced the operation of the company's various liquid level instruments and flow instrument inspection and calibration laboratories.
