Transducers are devices that convert one form of energy into another, playing a crucial role in various applications. For example, a microphone transforms sound waves into electrical signals, while a speaker does the opposite by converting electrical signals back into sound.
These devices are essential in fields like telecommunications, medical imaging, and automotive technology. By enabling the interaction between physical phenomena and electronic systems, transducers facilitate the accurate measurement and control of various processes, enhancing our ability to gather and interpret data from the environment.
