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.
