Does signal generator and piezo controller drive PZT have the same effect?
Does function signal generator and piezo controller drive piezo actuator have the same effect? Someone often consult: What is the difference between function signal generator and piezo controller? Could a function signal generator be used to drive piezo actuator? I use a signal generator to drive piezo actuator, why is there no effect? Is it broken? In this issue, we will give you a detailed introduction to the two products of function signal generator and piezo controller in terms of parameter design and so on. I believe you will eventually get the corresponding answer. Piezo Actuator Before introducing the parameters, let's know about the piezo actuator for everyone.
Piezo actuator is functional materials that can convert electrical energy into displacement. When the piezo crystal deforms under the action of external force, the charge proportional to the external force can be generated on the crystal surface. This phenomenon of polarized charge on the crystal surface due to the action of mechanical force is called the positive piezoelectric effect. At the same time, when the piezo crystal is placed in an external electric field, the crystal will deform due to the action of the electric field. The magnitude of the deformation is proportional to the strength of the external electric field. This phenomenon is caused by the deformation of the piezo crystal due to the action of the electric field. It is called the inverse piezoelectric effect. All the applications of piezo actuator are based on the above-mentioned positive piezoelectric effect and inverse piezoelectric effect. The main application in the field of piezo nanopositioning is the inverse piezoelectric effect.
