Electromechanical effects refer to the interaction between electrical and mechanical systems. This phenomenon occurs when an electric field causes a mechanical deformation in materials, or when mechanical stress generates an electric charge. Common examples include piezoelectric materials, which generate voltage when compressed, and electromagnetic actuators, which convert electrical energy into motion. These effects are widely utilized in various applications, such as in sensors, actuators, and transducers. For instance, in speakers, electrical signals create vibrations in a diaphragm, producing sound. Understanding electromechanical effects is crucial for developing advanced technologies in robotics, telecommunications, and medical devices.
