On application of pressure certain crystals can produce electric signals. This phenomenon is known as

Options

AFerrielectricity
BFerroelectricity
CPeizoelectricity
DPyroelectricity

Correct answer

C. Peizoelectricity

Step-by-step solution

When polar crystal is subjected to a mechanical stress, electricity is produced - a case of piezoelectricity. Reversely, if electric field is applied, mechanical stress is developed. Piezoelectric crystal acts as a mechanical electrical transductor.
