Accelerometers are motion sensors that measure acceleration forces (static or dynamic) along one or multiple axes. These devices convert mechanical motion into electrical signals, enabling quantitative analysis of vibration, tilt, shock, and dynamic movement. As core components in modern sensing systems, accelerometers play critical roles in consumer electronics, industrial automation, automotive safety systems, and aerospace navigation.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Capacitive MEMS | High sensitivity, low power consumption, digital output | Smartphones, wearable devices |
| Piezoelectric | Self-powered, excellent frequency response | Vibration analysis, impact detection |
| Piezoresistive | High shock tolerance, analog output | Automotive crash testing, industrial monitoring |
| Servo (Force-Balance) | Ultra-high precision, low noise | Inertial navigation, seismic monitoring |
| Optical MEMS | Immune to electromagnetic interference | High-precision scientific instruments |
Typical accelerometers consist of: - Seismic mass with specific inertial properties - Elastic suspension elements (springs or beams) - Displacement detection circuit (capacitive, piezoelectric, or resistive) - Temperature compensation circuitry - Signal conditioning electronics - Protective housing (metal/ceramic/polymer) Modern MEMS devices integrate microstructures on silicon substrates with digital interfaces (I2C/SPI).
