What is MEMS technology?Micro-Electro-Mechanical Systems (MEMS) is a technology that can be defined in its most general form as miniaturized mechanical and electro-mechanical components (i.e. devices and structures) fabricated using micromachining techniques. MEMS technology sensors are low-cost, high-accuracy inertial sensors that can be used in a variety of industrial applications. Беспроводной модем ЛораMEMS, or microelectromechanical systems, is a chip-based technology in which a sensor consists of a suspended mass between a pair of capacitive plates. This suspended mass creates a difference in electrical potential when the sensor is tilted. The resulting difference is then measured as a change in capacitance. Technical characteristics of MEMS technology①AdvantagesMEMS technology does have some advantages of its own. MEMS sensors offer convenient functionality and can be used with all other sensor families without any space constraints. In addition, MEMS utilizes very compact micro-machine components that are so small that each MEMS sensor fits easily into the palm of your hand. The MEMS sensor has IP67 sealing. This is because the sensor needs to be able to withstand extreme temperatures from -40º to +85ºC. Most industries that use MEMS sensors operate in extreme temperatures. Moreover, this sealing enables the sensor to be temporarily submerged in shallow water, allowing monitoring of pitch and roll applications at sea and on the sea floor. Other electrolytic sensors may have higher accuracy but are generally more sensitive to temperature.Another advantage of these MEMS sensors is their resistance to shock and vibration. MEMS sensors may not be the most durable in shock-absorbing environments, but MEMS inclinometers have 10grms vibration resistance at 10-1000Hz and accelerometers have 100G shock resistance. Therefore, these sensors cannot be used in highly shocking scenarios such as military applications, but they can withstand industrial measurement and control, drilling equipment, and some geotechnical monitoring. ② DisadvantagesWhile MEMS sensing technologies are useful, they do have some limitations. Typically, MEMS sensors have large drifts over the entire temperature range. This may be of concern for those without temperature compensation or heating capabilities. Also, MEMS sensors typically have lower accuracy relative to other traditional and more expensive sensors. Therefore, you should always determine exactly what you need to measure before buying. MEMS sensors are ideal for applications that do not require the highest precision, such as industrial automation, platform control, position control, and pitch and roll measurements. This is why MEMS electrolytic sensors are perfectly suitable for many different fields at low cost. The application direction of MEMS technologyMEMS is the integration of technologies such as microsensors, microactuators, and microelectronics onto a single microchip, which promises to be one of the most important technological breakthroughs in the future.This will enable the development of smart products by augmenting the computing power of microelectronics with the sensing and control capabilities of microsensors and microactuators. Sensors gather information from the environment by measuring mechanical, thermal, biological, chemical, optical, and magnetic phenomena. The electronics then process the information obtained from the sensors and with some decision-making ability direct the actuators to respond by moving, positioning, regulating, pumping, and filtering to control the environment for some desired result or purpose.последовательный модульFurthermore, because MEMS devices are fabricated using similar volume manufacturing techniques as ICs, unprecedented functionality, reliability, and complexity can be placed on small silicon chips at a relatively low cost. MEMS technology is very diverse and rich in both its intended application areas and the way devices are designed and fabricated. MEMS is already revolutionizing many product categories by enabling complete systems on a chip.
