Capacitive Accelerometer

Definition - What does Capacitive Accelerometer mean?

A capacitive accelerometer is a type of accelerometer device that measures the acceleration on a surface using capacitive sensing techniques. It has the ability to sense static and dynamic acceleration on equipment or devices - enforced by human or mechanical forces - and converts this acceleration into electrical currents or voltage.

A capacitive accelerometer is also known as a vibration sensor.

Techopedia explains Capacitive Accelerometer

A capacitive accelerometer senses and records vibrations produced on a device or surface. It is composed of an oscillator or any stationary component that has the ability to store capacitance. When these components move or are moved, the generated capacitance or energy is sensed by the capacitive accelerometer's native sensors. The sensors, in turn, are connected to an electrical circuitry, which measures the intensity and magnitude of the acceleration with respect to the electrical current.

Capacitive accelerometers are widely implemented in computational and commercial applications, such as airbag deployment sensors in automobiles, human computer interaction (HCI) devices and smartphones.
