Many older people want to keep living at home, and their families want to know they're okay. mmWave radar senses presence, movement and rest without wearables or cameras — so help comes when it's needed, and privacy stays intact.
For an older person living alone, a fall that goes unnoticed for hours can be more dangerous than the fall itself.
Many falls happen in the bathroom, where cameras aren't acceptable and emergency pendants are often taken off. Radar works through steam and shower curtains, recognising both the fall and the stillness that follows, so family can be alerted right away.
Some older people get up at night and head out alone — and families often find out only in the morning.
A radar near the front door notices when someone walks toward it and leaves, without a camera pointed at the entrance. Alerts can follow the household's routine — only at night, or only when no one else is home.
Families want to know a loved one is sleeping well, but cameras in the bedroom and devices worn to bed are hard to accept.
A bedside radar senses when someone is in bed, how restless the night is and how often they get up — through blankets, without touching them. Night after night, it builds a picture of rest that families and carers can check.
Changes in daily life — fewer trips to the kitchen, more hours in bed — are often the first sign that someone needs more support, but they're easy to miss from afar.
Radar sensors in a few rooms learn the household's normal rhythm of movement, without recording images. When the pattern shifts over days or weeks, family members get a gentle heads-up, while the person keeps their independence.
Illustrative scenario. Actual performance depends on sensor configuration, installation and system integration.
Wearables get taken off, cameras feel intrusive, and motion sensors miss someone lying still. Radar notices what matters, with nothing to wear and nothing watching.
