Piezoelectricity refers to the phenomenon where certain materials generate an electric charge when subjected to mechanical stress or pressure. Conducting a piezoelectricity test on a data cable involves evaluating whether the cable exhibits any piezoelectric properties under specific conditions.
General Test Procedure
-
Assess the voltage differential on the cable prior to mechanical stress.
-
Apply a static mechanical load on the cable center point and measure the voltage differential.
-
Compare the measured data with the baseline measurements taken before the stress application. Assess whether the data cable displays any significant piezoelectric properties. If there is a noticeable change in the electrical response during the test, it indicates the presence of piezoelectricity in the cable.
