Senior reassurance · Contactless WiFi sensing
No cameras.
Watching over the hours spent alone
Evawave looks in on the living spaces of older adults who live alone through WiFi signals — nothing to wear, no cameras — and alerts care teams and families when movement stops for longer than usual.
01The problem
The danger isn't only the moment of a fall — it's the time no one knows
When something happens to an older adult living alone, calling for help is hard. And usually it comes to light only at the next scheduled check.
Moments when no one can call
Emergency buttons help when they can be pressed. Moments of clouded consciousness or an out-of-reach button stay uncovered.
The gap between checks
When people check at set times, whatever happens in between — overnight, for example — surfaces only at the next check.
Devices that must be worn
A watch works only when it is worn, and a camera feels like surveillance at home. What is burdensome every day is hard to keep using.
02Technology
Reading a space through WiFi signals — no cameras
When a person moves, the WiFi signals passing through a space shift slightly. Evawave's contactless sensing reads these changes to watch over multiple rooms at once, and we have filed two patents on this technology.
Plug it in
Small devices plug into outlets in the main rooms. The person living there has nothing to wear or operate.
Read through WiFi
Changes in WiFi signals show movement across multiple rooms, even through walls. No video or audio is involved.
Alert when it matters
When movement stops for longer than usual, an alert goes to the care team's dashboard and the family's caregiver app.
Contactless sensing of everyday signals
With nothing to wear and nothing to operate, it reads movement and activity changes in the home and notifies caregivers at moments that warrant a check. We ship only what has been verified in real homes.
Wall-penetrating WiFi sensing
We have filed a patent on technology that watches over multiple rooms at once with WiFi signals. We are extending it step by step toward finer detection, such as suspected-fall alerts.
Wi-Fi sensing — reading changes in a space through Wi-Fi signals — is a field gaining validation worldwide, with the international standard IEEE 802.11bf formally published in September 2025. Evawave is applying this technology to senior reassurance monitoring. The labels above describe the technology field and patent filing status; they do not mean that Evawave products are IEEE-certified.
Evawave is not a medical diagnostic device. It is a contactless monitoring solution that estimates everyday activity signals and possible anomalies from sensor data, helping caregivers check on their family member.
03Who it is for
For care settings and families, each in their own way
The sensing technology is the same, but who checks — and how — is different. Choose the one that fits you.
