Most of us carry a device with several of them in our pocket, but few of us know how they work or have given them a second (or even first) thought. Measuring distance electronically is far less practical than we would initially think. For something so easy…

Our modern world—smartphones, electric cars, wind turbines, the Internet of Things, AI, drones—relies upon humble transducers. Transducers, technically speaking, are any devices that convert energy from one form to another, whether that be mechanical to electrical, electric to chemical, or chemical to EM—any form of energy into another. In their purest form, any heat engine,…
