Terahertz electronics: The last frontier

Summary form only given. Sensors add intelligence to systems which represent a broad class of devices incorporating functionalities like sensing, actuation, and control. They are the core of smart components and subsystems; then, the challenge in the realization of such smart systems goes beyond the design of the individual components and subsystems and consists of accommodating a multitude of functionalities, technologies, and materials to play a key role to augment our daily life.
