piezoelectric effect

In 1880 AD, the French physicist brothers Jacques and Pierre Curie found that when mechanical stress was applied to the crystal, a shift in charge was produced, I .e.piezoelectric effect.

crystal oscillatorpiezoelectric effectIt means that when mechanical pressure is applied to the crystal oscillator, the crystal oscillator will generate an electric field;

Conversely, if mechanical pressure is applied to both sides of the wafer, an electric field will be generated in the corresponding direction of the wafer;

This physical phenomenon is the so-called piezoelectric effect.

The following table summarizes the relevant information about the piezoelectric effect of the crystal oscillator:

This effect allows the crystal to convert mechanical energyelectrical signal, Or conversely, convert electrical signalsMechanical energy. This characteristic makes crystal oscillator play a vital role in many electronic devices, especially inHigh frequency stabilityin the application.
