Part 2/9:
The testing begins with an overview: the experimenter references the original barium titanate cylinders sent to Japan’s Kyoto Institute of Technology, where they were used at approximately 18.5 kHz for field stress detection. The goal is to compare the sensitivity of these original cylinders with more recent, ruggedized versions that resemble sonar transducer components.
The setup involves basic testing tools—oscilloscopes, spectrum analyzers, and simple contact experiments—aimed at evaluating the material's response to mechanical stimuli like squeezing or tapping. The experiment emphasizes simplicity over high-frequency analysis, focusing instead on the tangible sensitivity of these cylinders to physical pressure and sound vibrations.
