micro sensors with new technologies and processes have expanded their application fields, met higher requirements, and become the driving force for the development of the sensor market

according to relevant reports, the global sensor market was $50.6 billion in 2008, and it is expected that the global sensor market will reach more than $60billion by 2010. In recent years, the integration with semiconductor technology has become an important driving force to promote the development of sensors. This last kind of integration makes the performance of sensors more powerful, but the volume is getting smaller and smaller, giving birth to micro sensors. The emergence of micro sensors makes it possible to apply sensor components in many fields that cannot be applied to sensors, thus providing conditions for the intellectualization of system products. At the same time, the expansion of sensor applications has brought more market demand. In recent years, the popularity of emerging micro sensors based on MEMS technology, such as acceleration sensors, angular velocity sensors, wireless sensors, biosensors, optical sensors and so on, continues to bring new growth points to the sensor market. For example, the recently emerging sensing concept is closely related to micro wireless sensors, which also benefits from the development of sensing.

technological innovation of micro sensor

micro sensor sounds like a small sensor, but in fact, it is not the product of simple physical reduction of traditional sensors. According to experts, it is a new generation of sensor device prepared by MEMS and other processing technologies with new working mechanism and physicochemical effect, using materials compatible with standard semiconductor process. It has the characteristics of miniaturization and integration, which can greatly improve the performance of the sensor. Its appearance solves the problem that the traditional sensor cannot adapt to the high-speed, high-density, small volume and low-cost signal processing devices made by semiconductor technology in terms of performance, size and cost because its manufacturing process is incompatible with semiconductor technology

in order to meet the higher requirements of the market, sensor manufacturers have made continuous progress in technology and technology, and their products have become more differentiated. For example, Epson's micro sensors are made by qmems process. Kaihong Sakai, deputy general manager of Epson (China) Co., Ltd., told China Electronics News that qmems is a unique new technology that combines the two keywords of quartz and MEMS. It is a crystal fine processing process realized by using photosensitive printing and processing technology. The traditional machining process is to cut the crystal substrate, put the crystal sheet and abrasive together in the container, rotate and grind, and then chamfer the crystal. Now it has reached its limit in many ways. Epson uses photosensitive printing technology to fine process the crystal. Compared with mechanical processing, its process greatly improves the stability, realizes the ultra miniaturization of the product, and also greatly improves the crystal characteristics

the MEMS acceleration sensor of Meixin semiconductor adopts the thermal convection technology. Zhang Jiafu, the marketing director of Meixin semiconductor, said that this technology is different from the capacitor technology, which can make the product have higher impact resistance and reduce the failure rate, and the CMOS process it uses also significantly reduces the cost

application expands to consumer electronics

the development of the application market also provides a good stage for micro sensors. Whether in the automotive, machinery manufacturing industry, industrial process control, or household and consumer electronic products, micro sensors are more widely used than before

micro sensors based on MEMS technology have many characteristics, such as improving signal-to-noise ratio and sensitivity, and realizing complex multi-step nested loop control It can set automatic return, automatic judgment of fracture, automatic zeroing and other functions, with array, high integration and good compatibility. And because it uses the mature silicon micro semiconductor processing technology to process and manufacture, it can be mass produced and reduce the cost, so it is popular in many application fields

meas' MEMS sensors are widely involved in various test fields such as pressure, acceleration, temperature and humidity, magnetoresistive displacement, and various integrated micro sensors for industry-specific applications. Cheng Yonghong, the technical development manager of meas company, gave several typical application examples in one breath, such as the invasive blood pressure transmission type II sample for medical surgery, which is a rectangular strip sample sensor with equal cross-section, the gas mass flow sensor for high-end gasoline vehicles, the temperature and humidity integrated sensor for automobile (especially hybrid power vehicles), the oil sensor with micro machining tuning fork technology The vehicle exhaust system uses an integrated temperature, humidity and pressure measurement sensor, etc

Zhang Jiafu believes that MEMS sensors have long penetrated the markets of industry, automobile and navigation systems, because new products based on MEMS technology provide a very low cost, thus benefiting the relevant markets. The future application trend of MEMS will be in home and consumer electronics, because they are the fastest-growing and largest market

however, at present, the fastest growing market in the global sensor market is still the automotive market, followed by the process control market

the wireless market is growing rapidly

IOT or sensing has recently developed in some regions, making its concept a hot spot in the industry. As one of the key devices, wireless sensors will also play an important role in IOT or sensing

sensor manufacturers naturally attach great importance to emerging markets. They are closely observing the development of the market, looking forward to the introduction of IOT standards, and are also ready to enter this market. Zhang Jiafu said that IOT is a new application and is being popularized recently. But in fact, the intelligent sensor network of IOT is not a new concept. RFID (radio frequency identification) and ZigBee were created for this purpose. Now bandwidth, infrastructure and sensor technology are finally catching up, ready for this type of application. He said that for IOT, there are different types of system architectures and implementation methods. They are evaluating what systems and applications Meixin products can be used in and can create the most value for customers

meas also attaches great importance to the field of wireless sensors. They have set up special business departments and R & D centers. Their first generation of pressure, temperature and humidity wireless sensors have been adopted in important industrial fields in the U.S. and European markets. Cheng Yonghong told them that they are independently developing chip level low-power solutions, which will occupy a considerable market share in the emerging but increasingly popular international and domestic wireless sensing field

at present, IOT has just begun to develop, and some people in the industry are skeptical. They believe that the wide interconnection of IOT is difficult, the standards are difficult to unify, and it is not easy to achieve. However, for sensors, the emergence of IOT has brought new market opportunities and innovative ideas for applications
