Ferroelectric testing is a key method for studying the properties of ferroelectric materials and finds wide applications in numerous fields such as power, electronics, communications, and sensors. Under an applied electric field, ferroelectric materials can undergo polarization and maintain this polarized state. Therefore, investigating their polarization behavior, electromagnetic characteristics, and thermal properties is crucial for both material development and practical applications. Through ferroelectric testing, not only can the polarization mechanisms of materials be deeply revealed, but their performance under various environmental conditions can also be systematically evaluated. This provides critical insights for material modification, optimization, and device structure design.
