Part 3/9:
Initial Tests with Original Cylinders
The first cylinders tested are the original pieces, including one that was used at Kyoto. The experimenter applies varying amounts of pressure (around six to ten pounds) to observe the electrical signals produced, recorded via an oscilloscope. The signals are triggered by squeezing or tapping the cylinders, indicating their piezoelectric response.
The sensitivity is apparent: gentle pressure and taping produce measurable signals, suggesting high responsiveness suitable for sensing applications. The test explicitly notes the absence of advanced calibration, but the consistent signal output suggests these cylinders are reliable for detecting mechanical energy.
