Fujitsu Limited has released the world’s first(1) millimeter wave band radio sensor in Japan today. Designed to improve safety and privacy in high-risk areas, including care and assisted living homes and public accessible toilets – where old-fashioned camera technology would lead to privacy issues.
Fujitsu’s AI technology has been used in the system to analyze even slight human movements like bodily vibrations such as breathing and muscle movements with the use of millimeter-wave radar. This state-of-the-art feature makes it possible to detect anomalies that would normally go undetected with other motion-detection systems.
The system can work very well in low light, while maintaining 24/7 surveillance without burdening staff (especially on ground staff during night and early hours, where staff are the fewest). And it does this all without ever tracking video or capturing any personal information, to fully protect individuals’ privacy.
The system is armed with an intelligent alarm notification feature ensuring instant alarm under particular circumstances.
Namely, such cases may involve identifying when a person falls down and then stays in a position for a time until a determination is made that no movement is detected or continues to stay in a location longer than expected (e.g. in a location deemed abnormal) or other unusual events such as variation from a regular sleep pattern, as such indications of an abnormality may suggest an inadequate response to the accident.
The notifications may be selectively delivered to specific recipients, thus promoting quick response times and ensuring timely arrival of assistance to the user.
Before the official release, Fujitsu successfully conducted verification trials for the millimeter-wave radar monitoring technology with AEON MALL Co., Ltd. in restrooms, and around fall detection experiments for hospitalized patients with Wakaytama Medical University.
These collaborations highlight the system’s real-world applications and potential to transform safety monitoring in contexts such as where privacy and immediate response are vital. This product is not a medical device.
