Part 4/6:
Notably, Paul mentions that sometimes the sparks can be more substantial, indicating variability in energy release. He experiments with wiring the system to visualize the sparks more clearly, hinting at potential uses in high-voltage or energy storage applications.
Temperature Effects and Condensation Observations
To examine the influence of temperature on the piezoelectric behavior, Paul places the cylinder in a freezer, cooling it down significantly. After several minutes, he retrieves the cooled sample, observing condensation buildup—a physical reminder of the temperature change. His measurements show a voltage drop to about 1.175 volts, consistent with the expectation that cooling diminishes the material’s electrical output.
