Millimeter-wave radar sensors have seen widespread adoption in recent years, particularly in applications such as autonomous driving, security surveillance, and medical diagnostics. So, do millimeter-wave radar sensors pose any health risks to humans?

First, we need to understand the operating principle of millimeter-wave radar sensors. These sensors emit electromagnetic waves in the millimeter-wave band; when these waves encounter an object, they are reflected back. By measuring the time and intensity of the reflected signals, the sensor can determine the object’s position, velocity, and shape. Because millimeter-wave electromagnetic waves have short wavelengths, high frequencies, and substantial energy, some people worry that they may pose health risks to humans.

Hengyi Technology’s 60 GHz millimeter-wave radar sensor boasts an exceptionally wide detection range, enabling precise fall detection whether in wet, slippery areas like kitchens and bathrooms or in open spaces such as bedrooms and living rooms.


Hengyi Technology’s 60 GHz millimeter-wave radar sensor is an ideal solution for fall detection. It not only accurately captures human‑body information and enables non‑contact posture monitoring, but also triggers fall alarms, significantly enhancing our quality of life.

Multi-scenario applications—contactless detection, no image generation, and protection of caregivers’ privacy.

However, according to current scientific research, millimeter-wave radar sensors have a relatively minor impact on the human body. Although millimeter-wave electromagnetic radiation carries a certain amount of energy, its energy density is far lower than that of visible light or ultraviolet radiation. Consequently, millimeter-wave radar sensors do not pose an immediate risk of harm to humans.

In addition, millimeter-wave radar sensors typically adhere to specific safety standards during both design and operation. For instance, their transmit power is strictly limited to ensure no adverse effects on human health. Moreover, these sensors generally emit electromagnetic waves only when necessary, thereby minimizing potential exposure to humans.

Of course, although millimeter-wave radar sensors have relatively limited effects on the human body, we must remain vigilant. In the future, as the applications of millimeter-wave radar sensors continue to expand, we will need to pay closer attention to their potential impacts on human health and adopt even stricter safety measures to safeguard public well-being and safety.

In summary, millimeter-wave radar sensors have a relatively minor impact on the human body, but vigilance remains essential. In future applications, we must continue to intensify research and exploration to ensure that these sensors, while offering convenience, do not adversely affect human health and safety.
