MEMS sensor: Microelectromechanical system

Microelectromechanical system (MEMS) sensor is a miniaturized A sensor that integrates mechanical and electronic components on a single chip. It is usually made of silicon-based substrates and has the advantages of small size, light weight, and low power consumption.

The principle of MEMS sensor

MEMS sensor utilizes the mechanical properties of micro-electromechanical structures to respond to changes in physical parameters. When the measured physical parameters act on the MEMS structure, mechanical deformation or displacement will occur. These deformations or displacements will be converted into electrical signals through conversion mechanisms such as capacitance, resistance or piezoelectric effects, and then processed through signal processing circuits to obtain digital output of the measured parameters.

Types of MEMS sensors

MEMS sensors can be divided into many types based on the physical parameters detected, including:

• Acceleration Gauge: Measures acceleration
