Understanding Unimorphs: A Deep Dive into Piezoelectric Technology

Unimorphs are integral to many piezoelectric applications, and understanding their function can provide valuable insights into the capabilities of piezoelectric technology.

What is a Unimorph?

A unimorph is a piezoelectric disc consisting of one active piezoelectric layer and one non-active layer. The active layer is made of piezoelectric material, which generates an electric charge in response to mechanical stress. On the other hand, the non-active layer is typically made of a non-piezoelectric material and serves as a base and stabilizer for the piezo disc.

How Does a Unimorph Work?

When a voltage is applied to the active layer of a unimorph, it deforms in a single direction. Depending on the application, This deformation can generate mechanical movement or electrical output. The non-active layer of the unimorph helps to control the direction of this deformation, ensuring that the unimorph bends or contracts in the desired manner.

Applications of Unimorphs:

Unimorphs are used in a wide range of applications across various industries. They are commonly found in sensors and actuators, which convert electrical energy into mechanical energy, or vice versa. For example, in a sensor application, a unimorph might be used to detect vibrations or changes in pressure. When the unimorph experiences a mechanical force, it deforms, generating an electric charge that can be measured and interpreted.

In an actuator application, a unimorph might be used to create physical movement. When a voltage is applied to the unimorph, it deforms, causing a mechanical movement that can be used to perform a physical task. This could be anything from opening a valve in an industrial system to creating sound in a speaker.

Why Choose Unimorphs?

Unimorphs offer several advantages in piezoelectric applications. They are highly efficient, with low power consumption and fast response times. Another advantage is that they can be customized to meet specific requirements, which makes them suitable for a wide range of applications. Furthermore, unimorphs are robust and reliable, capable of operating in harsh environments and extreme temperatures.
