Electricity obtained from pressure is referred to as what effect?

Electricity obtained from pressure is referred to as the piezoelectric effect. This phenomenon occurs in certain materials, known as piezoelectric materials, which generate an electric charge in response to mechanical stress. When these materials are compressed, twisted, or otherwise deformed, they produce an electric voltage due to the rearrangement of charge within their structure.

The piezoelectric effect is widely used in various applications, including sensors, actuators, and electronic devices, such as microphones and speakers, where the conversion between mechanical energy and electrical energy is essential. Understanding this effect is crucial for linemen and electrical technicians who may work with equipment that utilizes piezoelectric materials in various applications, from sensing technology to energy generation systems.
