Pilot Overview

Patient Safety Grid Device 1 — a wearable band, nurse console, and family app for hospital inpatients.

What is PSG Device 1?

A reference-design wearable band worn by hospital inpatients, paired with a nurse console for real-time monitoring and a family app for visibility. The system uses IMU/accelerometer, Wi-Fi/BLE beacon positioning, and optical PPG sensors to detect 9 functional requirements — from fall detection to heart-rate monitoring.
