Key Trends & Drivers

• Rising Adoption in Surveillance & Security Systems

The rising emphasis on public security and safety has been elevating the vitality of terahertz technology in surveillance and screening systems. Terahertz waves, unlike the ionizing methods, are harmless and could safely penetrate plastics and fabrics, which would help in detecting concealed items like explosives or weapons. This online trend is compelling both – private entities and governments to adopt terahertz technology as a non-invasive alternative to conventional millimeter-wave and X-Ray scanners. For instance – In June 2025, Cambridge Terahertz Inc. did receive an SBIR (Small Business Innovation Research) Phase II award worth 1.25 Million USD from the U.S. National Science Foundation for developing a terahertz imaging radar for contactless, real-time weapon detection in educational and public transit facilities.

Also, the NSF, in 2023, sanctioned 274,927 USD to the above-mentioned company to create a portable terahertz radar system for enforcement of law that is capable of detection of non-metallic threats such as ceramic knives and 3D-printed firearms, thereby offering a cost-effective, compact alternative to traditional airport scanners.

What’s trending in the Terahertz Technology Market?

Terahertz imaging is in higher demand due to its high-bandwidth applications. Defense & security is the sector wherein terahertz technology is utilized for non-invasive screening. In the healthcare sector, terahertz imaging is used for earlier detection of cancer, tissue analysis, and dental diagnosis. Mid-frequency systems (105 THz) are dominating the market, but higher frequency systems (above 5 THz) are witnessing a rise in demand for applications that need utmost precision. For example – semiconductor research and meteorology. In the communication sector, terahertz frequencies facilitate ultra-high-speed data transmission for IoT devices, autonomous vehicles, and data centers.

Key Threats

One of the key restraints to the terahertz technology market is complexity pertaining to the integration of terahertz systems into the existing communication, industrial, security, and medical infrastructures. Terahertz systems, unlike the well-established technologies with standardized interfaces and protocols, do demand stabilized calibration, custom components, and tailor-made software, which result in increasing the costs as well as technical challenges for the end-users.

Several legacy systems are incapable of operating at higher frequencies/bandwidths needed by terahertz devices, thereby necessitating sizable retrofitting/system upgrades. Such a challenge regarding integration is critical, especially in sectors such as telecommunication, wherein reliability is necessary. As a consequence, the organizations may avert or delay adopting terahertz in spite of its advantages, slowing penetration and creating a gap between commercial deployment and innovation.

Opportunities

The switch toward 6G wireless networks does present a sizable opportunity for growth of the terahertz technology market. The major objective of 6G is that of delivering data rates exceeding 1 TB/second, proper device connectivity, and ultra-low latency – all of which need frequencies beyond the millimeter-wave spectrum that constitutes 5G.

Terahertz waves facilitate quicker data transmission with advanced applications like immersive extended reality (XR) and real-time holographic communication. With 6G standardization efforts witnessing technical advancements, terahertz technology is turning out to be one of the key enablers for spectrum research, prototype development, and field trials.
