601.1691.074 Application Field and Working Principle

601.1691.074 is a document number assigned to the publication “Field Theory of Laser MEMS” by researcher Robert Yule. This document describe the principles of a microelectromechanical systems (MEMS), specifically about its application field and working principle.

What is Microelectromechanical Devices

Microelectromechanical systems (MEMS) are tiny structures that merge the electronic and the mechanical worlds into one. They are fabricated using techniques familiar to both disciplines and might include components from both. The MEMS technology especially laser micro-machining technology is used to design structures such as accelerometers (acceleration sensors), pressure sensor, flow sensors, gyroscopes, actuators, timers etc. Thus, MEMS technology can become an integral part of a product or an application.

MEMS Application Field

MEMS have found a place for themselves across many industries with applications ranging from consumer electronics, automotive, aerospace, healthcare, biotechnology and many other industries.

• In consumer electronics, MEMS are used for accelerometers, gyroscopes, microphones, touch screens, infrared detectors, cameras, and other advanced features.
• In automotive and aerospace, MEMS are being used for navigation, sensors to detect the wheel speed, pressure sensors for automatic braking, accelerometers for airbags deployment, acceleration, velocity measurement, and other important purposes.
• In healthcare, MEMS can be used for drug delivery, remote monitoring, micro motors and other medical devices.
• In biotechnology, MEMS can be used as nanosensors for medical diagnostics, cell selection process in genome research, drug discovery etc.

MEMS Working Principle

MEMS work on the principle of electrostatic forces and electrothermal motion control to detect changes in the environment or to effect changes in the environment. The most common type of MEMS device is the accelerometer. An accelerometer consists of a mass that is connected to a suspension system, which allows it to move freely. An electronic circuit is then used to measure the forces acting on the mass which is used to determine the acceleration of the mass. The same principle is applied for the other MEMS devices such as pressure sensor, gyroscopes, etc.

Conclusion

MEMS are versatile technologies that can be implemented in many different industries and applications. They come in many different sizes and shapes and can be customized for specific applications. The most common applications of MEMS involve sensors for measuring acceleration, pressure, temperature, flow, and other parameters. They operate based on the principle of electrostatic forces and electrothermal motion control and can sense changes in the environment or effect changes in the environment.
