What is the effect called when electricity is generated from pressure?

The effect in which electricity is generated from pressure is known as the piezoelectric effect. When certain materials, such as crystals, ceramics, or some polymers, are mechanically stressed or subjected to pressure, they develop an electric charge on their surfaces. This happens because the mechanical deformation causes a shift in the position of charges within the material, resulting in voltage generation.

The piezoelectric effect is utilized in various applications, such as sensors, actuators, and certain types of microphones and speakers, where conversion between mechanical energy and electrical energy is essential. Understanding this concept is crucial for apprentice linemen as it expands knowledge about different technologies and their applications in electrical systems.
