Tips: What is capacitive accelerometer sensor?
The capacitive accelerometer is a type of sensor used to measure acceleration by detecting changes in capacitance. It operates on the principle that when an object experiences acceleration, there is a relative movement between the sensor's internal components, typically a fixed electrode and a movable electrode (mass). This movement alters the distance between these electrodes, thereby changing the capacitance.
The sensor consists of a proof mass suspended between a set of fixed electrodes. When the accelerometer experiences acceleration, the proof mass shifts slightly from its equilibrium position. This shift causes a change in the capacitance between the proof mass and the fixed electrodes. The sensor's electronics then convert this capacitance change into a voltage signal, which is proportional to the acceleration.
Capacitive accelerometers are favored for their high sensitivity, low noise, and ability to measure both static (e.g., gravity) and dynamic (e.g., vibration) accelerations. They are commonly used in applications such as vibration monitoring, structural health monitoring, consumer electronics (like smartphones), automotive systems (e.g., airbags), and inertial navigation systems.
Their advantages include low power consumption, high resolution, and good stability over a wide temperature range, making them suitable for both industrial and consumer applications.
