MEMS Sensors, or Micro-Electro-Mechanical Systems sensors, are tiny devices that combine mechanical and electrical components on a single chip. They can detect changes in physical phenomena such as pressure, temperature, and acceleration. These sensors are widely used in various applications, including smartphones, automotive systems, and medical devices, due to their small size and low power consumption. The technology behind MEMS Sensors allows for the fabrication of intricate structures at a microscopic scale. This enables the creation of highly sensitive and accurate sensors that can perform multiple functions. As a result, MEMS Sensors play a crucial role in advancing modern technology and improving everyday devices.
