Piezoelectric Materials

Piezoelectric Materials: The pressure applied to the piezoelectric material in the lighter generates a spark.
 About: The piezoelectric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress.

• Reason: Atoms in these materials are arranged in a periodic pattern with alternating positive and negative ions.

• Effect of Pressure: Positive ions move in one direction, and negative ions in the opposite, creating a charge imbalance.
• Result: The material acts like a battery, generating an electric spark.
• Importance of Piezoelectric Materials: Enable sparks in lighters and similar devices.

o Their unique atomic structure is responsible for charge creation.
