Precision Contactless Heart Rate and Respiratory Rate Monitoring System

Radar sensor technology, particularly at the millimeter-wave (mmWave) range, offers innovative ways to monitor human health by leveraging electromagnetic waves to gather vital signs non-invasively. This non-contact approach is highly effective for measuring heart rate and respiratory rate, enhancing comfort for users by eliminating the need for physical sensors. This mmWave radar detects small body movements, such as chest expansion and contractions due to breathing, as well as micro-movements from heartbeats.

One of the key advantages of this technology is its ability to penetrate clothing and bedding, making it ideal for continuous monitoring in sleep studies, elderly care, and other medical applications. It also functions reliably regardless of lighting conditions or ambient noise, unlike optical or acoustic sensors.

This radar technology allows for immediate data collection, enabling quick responses in emergencies and optimizing overall performance.

Millimeter-Wave Radar (24GHz): This technology utilizes 24GHz millimeter-wave radar for continuous monitoring of heart rate (HR) and respiratory rate (RR), providing real-time and historical data through Cloud-based storage for easy access and analysis.

Measurement Distance: The device operates effectively at a measurement distance of 1.7 ± 0.2 meters between the radar's surface and the human body.

Heart Rate (HR) & Respiratory Rate (RR) Range: HR measurement range: 40 to 120 beats per minute (bpm) and RR measurement range: 5 to 50 breaths per minute (bpm)

Modulation Techniques: DSSS (Direct Sequence Spread Spectrum): Compliant with IEEE802.11b standards, used to reduce interference and improve signal reliability in wireless communications. OFDM (Orthogonal Frequency Division Multiplexing): Compliant with IEEE802.11g standards to ensures high-speed data transmission with the Wi-Fi systems.

Compliance: The system meets Singapore's IMDA compliance standards.

Connectivity & Accessibility: The system is Wi-Fi enabled, allowing data to be accessed through an app installed on mobile devices and tablets. The app provides real-time readings, along with pop-up notifications and alerts for any abnormal conditions. Data can also be viewed and analysed on PCs or laptops.

Dimensions & Power Supply: The radar device is compact, measuring 130mm × 90mm × 39mm (H × W × D), and is designed for low power consumption. It is powered by a USB-C adapter.
