Right Answer is:

Piezoelectric

SOLUTION

Piezoelectric substance generates the voltage when they are subjected to mechanical forces or stress along specific planes.

  • Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress.
  • One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect (the generation of electricity when stress is applied) also exhibit the converse piezoelectric effect (the generation of stress when an electric field is applied).
  • The most used piezoelectric materials are PZT, a ceramic containing lead titanate and lead zirconate, and PZLT, a ceramic of lead-lanthanum-zirconate-titanate.
  • Natural piezoelectric materials such as quartz (SiO2) and Rochelle salt (NaKC4H4O6–4H2O) are also used for piezoelectric transducers.
