Short Description
In the fabrication of piezoelectric materials, a polarization step is required to create and maintain a permanent electric dipole moment in the crystal structure of the material. The polarization process typically involves applying a constant or alternating high electric field to the piezoelectric material over a period of time. This field creates an electric polarization in the material by reorienting the crystal structure and aligning the electric dipoles in the direction of the electric field.
To measure the success rate of the polarization process, the polarization of the material is plotted against the applied electric field. The frequency response of the applied signal results in a hysteresis-shaped curve that is used to evaluate the piezoelectric properties of the material.
Due to the high electric fields and often unknown material parameters, manual control of such devices can be difficult. The goal of this work is to develop a microcontroller-based strategy for polarization and testing of piezoelectric polymers. It also aims to design the digital architecture in such a way that later studies will allow ML-based control of the system.
