Three building blocks that complement each other: the wearable on the wrist, wearable-free radio sensing in the room, and a local server that turns both into a clear picture for the caregiver.
Affordable wristband wearables capture heart rate, oxygen saturation (SpO₂) and movement. Because many low-cost models use proprietary Bluetooth protocols, we use a plugin architecture: each model gets its own adapter. This keeps the system model-independent and free of vendor lock-in.
CSI (Channel State Information) describes how WiFi radio waves propagate through a room and reflect off people. From these patterns the system detects presence, movement and suspected falls — with no wearable on the body. Ideal for people who cannot or do not want to wear a device.
A small appliance (mini-PC or ward server) brings all data together, stores it encrypted and serves the dashboard. The system is designed offline-first: it keeps running fully even without an internet connection. Encrypted replication to a provider data centre is optional.
Low-cost standard hardware instead of expensive special devices. Predictable per bed per month.
Data stays in the facility. GDPR-compliant, no cloud requirement.
Plugin architecture for new smartwatch models and sensors.
Keeps running offline. Local buffering during network issues.
Hints instead of data overload. Clear status per resident.
Surpluses flow back, in line with our mission, into care and development.
