Abstract

In recent years, terahertz radiation (THz = 1012 Hz) has attracted much attention due to its exceptional non-invasive and non-ionizing sensing capabilities. The sub-THz band (0.1–0.3 THz) and the THz band (0.3–10 THz) lie between millimeter waves (mm-waves) and light waves with the ability to harness their advantages. The capacity for these sub-THz and THz waves to penetrate deeply into dielectric materials combined with their high spatial resolution makes them well suited for biomedical applications, including in-vivo and ex-vivo experiments. The purpose of this chapter is to discuss how the sensors based on these frequency spectra can be used in various biomedical applications, classified into three major domains, i.e., diagnostics, imaging, and treatment, where they provide many advantages over the existing devices. Next, we will discuss the appropriateness of using photonics and electronics THz instruments in THz applications and the suitability of using electronics in the sub-THz regime. Finally, we'll look at artificial intelligence's function in enhancing the technology's versatility.
