The quartz accelerometer primarily uses the piezoelectric effect to measure acceleration. When the quartz crystal is subjected to acceleration or force, it undergoes slight deformation, generating electrical charges. These charge changes can be used to measure the magnitude and direction of the acceleration.
Basic Operating Principle:
- When the object accelerates, the internal structure consisting of a spring and mass block displaces. This displacement is sensed by the piezoelectric sensor attached to the quartz material, and the electrical charge response of the quartz crystal is converted into an acceleration signal.
- These signals are then processed and converted into a usable output (typically a voltage or current signal).
