Technical details and manufacturing context for 3-Axis Accelerometer

Definition

The 3-axis accelerometer is a component used in computer, electronic, and optical product manufacturing. It is a core part of an Inertial Measurement Unit (IMU) that detects and measures linear acceleration along three perpendicular axes (X, Y, Z). By converting mechanical motion into electrical signals, it provides motion data essential for navigation, stabilization, and orientation systems. The device operates on micro-electromechanical systems (MEMS) technology, where tiny capacitive plates or piezoelectric elements detect the displacement of a proof mass under acceleration, generating proportional voltage signals for each axis. Typical materials include silicon, polysilicon, and silicon dioxide. Key parameters include a measurement range of ±2 to ±16 g (selectable via register; lower range for higher resolution), sensitivity of 0.98 to 7.82 mV/g (scales with range setting), zero-g offset of ±30 mg (factory calibrated), nonlinearity of ±0.5% FS (full scale best-fit straight line), cross-axis sensitivity of ±1% (between orthogonal axes), bandwidth of 0 to 1000 Hz (user-selectable low-pass filter), supply voltage of 1.8 to 3.6 V DC (single supply), current consumption of 0.35 to 0.45 mA (at 3.3 V, normal mode), operating temperature of -40 to 85 °C (industrial grade), shock survival of 10000 g (0.1 ms half-sine), package size of 3×3×0.9 mm (LGA package), and weight of 0.05 g (typical). These values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The accelerometer is suitable for integration into systems requiring precise motion sensing, but designers should confirm compatibility with their interface and environmental conditions.

Working Principle

The accelerometer uses MEMS technology. Inside, a proof mass is suspended by tiny silicon springs. When the device experiences acceleration, the mass displaces relative to the fixed frame. This displacement changes the capacitance between interdigitated fingers or stresses piezoelectric elements. The change is converted into a voltage signal proportional to the acceleration for each axis. The signals are then amplified, filtered, and digitized for output. The measurement range and bandwidth can be configured via registers, allowing trade-offs between resolution and response speed.
