Miniaturization and manufacturing technology for the MEMS sensor industry manufacturers to open a new market. In order to monitor Sensor and combat the growing air pollution crisis in the city, people will soon see gas sensors in smart phones, wearable equipment and indoor monitoring equipment. The foundries will produce millions of gas sensor components in the next few years.

  Metal oxide gas sensor is the 1950 Kobe of Japan research and development results. This sensing assembly consists of a screen printed metal oxide layer heated to a high operating temperature (300-500 ° C). At this high temperature, oxygen is adsorbed to the surface and the conductivity of the material is adjusted, and the electrical conductivity of the material can be further adjusted when the atmosphere of the gas subsequently reacts with the adsorbed oxygen. These findings have created a multi-billion dollar industrial safety field, including commercial sensors for the detection of toxic gases and Fuel Rail Pressure Sensor monitoring of carbon monoxide, and some of the regulations from several countries. However, the large size and power requirements of such sensors make it still unable to be used in more commercial areas.

  Micro-electromechanical systems manufacturing processes have enabled MOS sensors to be mass-produced. Previously it could be used to print 200 sensors at the same time, but must be carried out in the laboratory with multi-layer printing materials. A new method of making and depositing materials by flame pyrolysis means that millions of sensors can be manufactured per day in a foundry. As a result of the use of micro-heating plate, the power requirements have been significantly reduced by ten times, today's sensor power consumption Temperature Sensor of less than 10mW. This new generation of chemical sensors, known as MEMS or CMOS gas sensors, minimizes the principle of MOS sensing to the component level. They are suitable for integration into many low-power handheld devices, such as mobile phones and flatbed and wear badges and jewelry. This sensor has the ability to detect contaminants in the air, which will have a significant impact on environmental gas sensors. IDTechEx expects the market to continue to expand and reach $ 3 billion in market size by 2027.
 
  Cambridge CMOS Sensors, with its innovative packaging technology to create the key to the sensor, in less than six years from the early stages of development and become one of the leading manufacturers of gas sensor technology. AMS quickly saw the rapid growth of the Chinese market, the smart phone and fitness tracker components used as an environmental monitor and monitor the alcohol content ABS Sensor  of the respirator. More traditional MOS gas sensor manufacturers eager to catch up with these emerging manufacturers. Japan Figaro Engineering has introduced a series of micro-sensors, with a combination of sensors mainly used for carbon monoxide monitoring.

  Sensirion sells its entire range of pressure sensors, concentrating on the development of various resources in the growing environment of gas sensors. These developments are driving the development of gas sensors towards consumer electronics devices Throttle Position Sensor  and are expected to grow significantly over the next five years. In order to monitor and combat the growing air pollution crisis in the global metropolitan area, it will soon be seen in smartphones, wearable equipment and indoor monitoring equipment.
