Types of MEMS Devices and Their Applications

Micro Electro Mechanical Systems or MEMS are associated with the development of microscale devices such as actuators, sensors, pumps, and gears. In other words, they are microscopic devices that combine with mechanical, electrical, and electronic components and perform a single function with the help of Microsystems Technology.

Many people consider MEMS technology as an advanced form of the traditional integrated circuit manufacturing process. However, both these terms are different to great extent. The major difference is that you can mechanical components such as springs, gears, and beams as well as electrical components such as inductors and capacitors with MEMS. On the other hand, traditional IC Technology can only help with insulators, transistors, and conductors.

What are MEMS Sensors?

Today, sensors are an essential part of the digital world. For instance, IoT devices use sensors to identify and execute tasks. Sensors play a vital role to connect digital electronics with the analog world. These components observe the effects of analog parameters and generate information.
