Part 4/9:
Following the initial tests, the experimenter disconnects the original cylinders and introduces ruggedized versions, which contain a ceramic plate encapsulated in a soft, rubbery coating. These are more durable and intended for rugged field use.
Remarkably, these ruggedized cylinders show even greater sensitivity under similar testing conditions. Applying modest finger pressure (around four pounds), the signals produced are comparable or superior to the original, indicating that the tougher, protective coating and material composition may enhance their piezoelectric response.
The Significance of Sensitivity
The tests highlight that these cylinders are remarkably responsive to mechanical stimuli, making them versatile for various applications:
