The generation of an electric charge in certain non-conductive materials (such as quartz or ceramics) when they are subjected to mechanical stress or pressure; also the reverse effect where an applied electric field causes the material to deform.

    The generation of an electric charge in certain materials (like quartz or ceramics) when they are subjected to mechanical stress or pressure.

    zh产生电荷

    • The piezoelectric effect is used in quartz watches to keep accurate time.
    • When you press a piezoelectric lighter, the crystal generates a spark.
    • Microphones often use the piezoelectric effect to convert sound waves into electrical signals.
