Скачать или смотреть Lecture 8 Comparison of Piezoelectric, Pyroelectric & Ferroelectric Materials

In this video, you will learn the difference and comparison between Piezoelectric, Pyroelectric, and Ferroelectric materials in simple English. These three types of dielectric materials are widely used in sensors, actuators, detectors, and memory devices.

Dr ESN Reddy clearly explains how mechanical stress, temperature change, and electric field influence polarization in these materials. You’ll understand key properties, working principles, examples, and applications of each — from quartz crystals and TGS to BaTiO₃. A comparison table highlights their unique behaviors and relationships, helping students grasp the concept quickly.

Perfect for Engineering Physics (JNTU R-25 syllabus), GATE aspirants, and anyone learning about smart dielectric materials.
By the end, you’ll see how these materials convert mechanical, thermal, and electrical energy effectively.
