Transducers are devices that bridge the gap between different energy domains. They take one form of energy, such as sound, light, temperature, or magnetic fields, and convert it into another form that can be measured, interpreted, amplified, or actuated. At a high level, the core idea behind a transducer is energy conversion: input energy is…
