Sensor innovation presents a trend of rapid growth

At present, the global sensor market shows a rapid growth trend in the ever-changing innovation. Some sensor markets such as pressure sensors, temperature sensors, flow sensors, and level sensors have demonstrated the features of a mature market. Relevant experts pointed out that the major technologies in the field of sensors will be extended and improved on an existing basis. Countries will compete to accelerate the development and industrialization of new generation sensors, and competition will become increasingly fierce.

Flow sensors, pressure sensors, and temperature sensors are the largest in the market, accounting for 21%, 19%, and 14% of the entire sensor market. The major growth in the sensor market comes from emerging sensors such as wireless sensors, MEMS (Micro-Electro-Mechanical Systems) sensors, and biosensors. Among them, the wireless sensor's compound annual growth rate in 2007-2010 is expected to exceed 25%.

The development of new technologies will redefine the future market of sensors, such as the emergence and market share of new sensors such as wireless sensors, fiber optic sensors, smart sensors and metal oxide sensors.

The rapid expansion of the sensor market According to the authoritative forecast, from 2004 to 2009, the global automotive sensor will show a growth rate of about 9%. In 2008, the market demand is estimated to reach 1.487 billion. The Chinese market is a hotbed for the development of automotive sensors. CCW Research's latest survey data show that in 2006, the sales volume of Chinese automotive sensors was 390 million U.S. dollars, a year-on-year growth rate of 42.8%. China Automotive 2007-2010 The compound annual growth rate of sensor market sales will exceed 35%. Among them, the market sales in 2007 will reach 540 million US dollars, a year-on-year growth rate of 36.3%; in 2009 its market sales will be close to 1.05 billion US dollars, an increase of 40.5%; 2010 market sales will exceed 1.32 billion US dollars, year-on-year growth 35.2%.

Professor Yuan Dahong of the Automotive Research Institute of Tsinghua University told the reporter: "The technical difficulty of ordinary car sensors is not great. At present, there are many applications in cars, such as temperature sensors, ABS wheel speed sensors, etc."

The rapid development of the Chinese sensor market has benefited from the rapid development of the auto market. At present, there are approximately tens to hundreds of sensors installed on an ordinary family car, and the number of sensors on luxury cars can reach as many as 200. In 2006, China’s auto market exceeded 7.2 million vehicles, of which passenger vehicles exceeded 5 million. In 2007, the domestic automobile sales will exceed 8 million, and the sales volume of vehicle sensors will also increase.

The stability of local sensors needs to be improved. The demand for sensors used in cars in North America continues to grow at an annual rate of 10%, and will reach the level of US$4.5 billion by the end of 2007. Among them, the use of car rollover sensors will increase, and it is expected that the compound annual growth rate of rollover sensor modules will reach 32.3% from 2003 to 2008.

With the continuous expansion of the size of automotive sensors in China, local companies must achieve breakthroughs in accuracy and reliability in order to achieve great development.

He Yujun, secretary-general of the Automotive Engineering Society of the China Automotive Engineering Society, told reporters: “The automotive sensor is the basis for many Auto Parts giants. At present, many domestic companies have improved their materials, design, and processes to produce a lot of basic materials. The sensor, but in terms of accuracy and reliability, there is still a big gap with foreign companies, many advanced technologies, especially the new design principles and core module technology of sensors, are still controlled by foreign companies. It is mainly followed by foreign countries, which clearly shows that companies have insufficient investment in research and development."

Traditionally, the market for automotive sensors is operating in OEM mode and usually does not need to directly face consumers. Therefore, auto manufacturers and first suppliers have the right to determine the relevant sensor specifications, in other words, for sensors. For suppliers, automakers and first suppliers are their customers.
