Exploring the Piezoelectric Properties of Barium Titanate: An Experimental Overview

In this engaging session, Paul demonstrates a series of experiments involving a barium titanate cylinder to explore its piezoelectric characteristics. Through hands-on testing, he reveals how the material responds to mechanical stress, temperature changes, and electrical phenomena.

Initial Setup and Measurements

Paul begins by outlining the dimensions of the barium titanate cylinder, preparing the setup with appropriate measurement tools. He activates his voltmeter and connects it across the cylinder to monitor the electrical output resulting from physical manipulations. His initial reading shows a voltage of approximately 0.045 volts, indicating a small but measurable electrical response.
