The rising demand for non-invasive imaging is expected to drive the growth of the terahertz technology market in the coming years. Non-invasive imaging involves diagnostic methods that allow visualization and analysis of internal body structures without surgical intervention. This demand is increasing due to the need for safer diagnostic procedures that reduce patient exposure to harmful radiation or invasive methods while still delivering accurate results. Terahertz technology supports non-invasive imaging by utilizing low-energy electromagnetic waves that can penetrate soft tissues, producing high-resolution internal images without harming the patient. It also enables real-time abnormality detection, aiding early diagnosis of conditions such as cancer and cardiovascular diseases. For example, in November 2023, the National Health Service (NHS), a UK-based government department, reported that England conducted 45 million imaging tests in the year ending March 2023, representing a 2.2% increase from the previous year’s 44 million tests. These included 10.3 million ultrasound scans, up 1.8%; 7.1 million CT scans, up 5.5%; and 4.1 million MRI scans, up 6.2%. This trend demonstrates how the demand for non-invasive imaging is boosting the adoption of terahertz technology.

Companies in the terahertz technology market are focusing on innovations such as next-generation 6G data transmission to deliver ultra-high-speed wireless communication and advanced imaging capabilities. Next-generation 6G refers to the sixth generation of wireless communication technology, offering extremely high-speed, low-latency, and reliable data transfer. This advancement enables applications such as real-time holographic communication, autonomous vehicles, and large-scale IoT connectivity, thereby increasing demand for terahertz technology. For instance, in January 2023, Canon Inc., a Japan-based multinational technology company, introduced a compact terahertz device that achieved the world’s highest output among 450 GHz semiconductor devices. The device integrates 36 synchronized active antennas onto a single semiconductor chip, resulting in around 10 times greater output and 20 times higher directivity compared to conventional models. Its compact design, nearly 1000 times smaller than traditional systems, allows for potential use in security scanning, high-speed imaging, and next-generation 6G data transmission without the need for bulky frequency multipliers or lenses.

In July 2025, TeraView Limited, a UK-based developer of terahertz light systems, formed a partnership with Doolim-Yaskawa to advance automotive paint inspection processes.
