Accelerometer Application:

An accelerometer is a type of sensor that measures force due to acceleration of the sensor. For illustrative purposes, imagine a wooden box with wheels and a concrete block inside. Now, imagine that somebody gives that box a generous push. If that person pushes and accelerates the box quickly enough, the concrete block inside the box might slide. This is because both the box and the concrete block have inertia and resist changes in their movement accordingly.

An accelerometer is a device that measures proper acceleration, the acceleration experienced relative to freefall. Single- and multi-axis models are available to detect magnitude and direction of the acceleration as a vector quantity, and can be used to sense orientation, vibration and shock. Micromachined accelerometers are increasingly present in portable electronic devices and video game controllers, to detect the orientation of the device or provide for game input.

PZT Material:

 

PZT ceramic is used in a wide variety of applications. Soft (sensor) PZT ceramic powders are typically used when high coupling and/or high charge sensitivity are important, such as in flow or level sensors; ultrasonic nondestructive testing/evaluation (NDT/NDE) applications; or for accurate inspections of automotive, structural or aerospace products. Material characteristics include a high dielectric constant; high coupling; high charge sensitivity; high density with a fine grain structure; a high Curie point; and a clean, noise-free frequency response.
 
Hard (high power) PZT ceramic powders are used when high power characteristics are required, including applications such as the generation of ultrasonic or high voltage energy in ultrasonic cleaners, sonar devices, etc. Important powder characteristics include a high piezoelectric charge constant (d33); a higher mechanical quality factor that reduces mechanical loss and enables a lower operating temperature; a low dissipation factor that ensures cooler, more economical operation; high dielectric stability; and low mechanical loss under demanding conditions.
