What Are The Different Types Of Piezo Actuators?

While using the piezo material, you need to know that it has a special type of ceramic that contracts or expands.

It will expand when an electrical charge is applied that will help in generating the force and motion. The piezo actuator provides the short stroked with a high frequency and offers a fast response many times.

It will also help generate the high forces relatively into the small size and give them a power-to-size ratio. It converts electrical energy into mechanical energy and is used as a motor. The actuator is used interchangeably and also produces the motion that will be parallel to the electrical field.

Longitudinal Actuator

  • It is also known as the piezo stack. It is used to create multiple piezo elements by layering or keeping in on top of each other. It helps in producing useful moments and forces.
  • It is used to generate the linear displacements from 0.1% to 0.15% of the actuator length. It has a high force density that results in the force usefully. It also has a high resonant frequency, making it best for dynamic applications.

Shear Actuator

  • The shear actuator is somewhat similar to the longitudinal version, which helps multiple layers for the piezo elements.
  • The elements are popularized horizontally; the displacement occurs in the horizontal plane. The height of this actuator is limited to the shear stresses and bending.
