Sensor is able to feel the provisions were measured according to certain rules and can be used to convert the output signal of the device or devices. Sensor as a cutting-edge technology of modern technology, modern information technology is considered one of the three pillars.
MEMS (Micro-Electro-Mechanical Systems) is the abbreviation of micro-electromechanical systems, MEMS technology is based on micro / nano based on is a micro / nano-materials design, processing, manufacturing, measurement and control technology, a complete MEMS by the micro-sensors, micro actuators, signal processing and control circuit, communication interface and power | voltage regulator composed of components such as integrated micro-device system.
MEMS sensor able to access to information, processing and implementation of the integrated to form a multi-functional micro-systems, thus greatly improving system automation, intelligence and reliability standards. It also allows manufacturers to incorporate all the features of a product integrated into a single chip, thereby reducing costs for mass production.
MEMS sensors are currently mainly used in two major areas of automotive and consumer electronics. According to ICInsight latest report is expected from 2007 to 2012, the global MEMS-based semiconductor sensors and brake sales will reach 19% of the average annual compound growth rate (CAGR), and in 2007 compared to 4.1 billion U.S. dollars, five will achieve the 9.7 billion in annual sales. 2007 to 2012, based on MEMS sensors and brake unit shipments will be 27% CAGR growth in 2007 shipments of 1.3 billion, will reach 4.3 billion after five years.
During the same period sensor / actuator unit shipments are expected to 23% CAGR growth in shipments in 2012 will reach 12.1 billion in 2007 shipments of 43 million items. Including various types of technology in sensor / actuator, its total market size is expected to reach 11.9 billion U.S. dollars. According to the report, based on MEMS-brake in 2007, will account for the overall sensor / actuator market share of 54%. People think that the era of things, MEMS sensors by virtue of its small size, low cost, and can be integrated with other smart chip, the great advantage of the sensor will become the main production technology.
