Contactless Vital Signs & Biometric Radar in ISACHealth

Continuous hospital patient monitoring typically requires uncomfortable wired electrodes and skin patches. ISACHealth formalizes ambient 6G cellular radar sensing, monitoring breathing, heart rate, and fall events through the air without attaching any sensors to the human body.

Core Engineering Areas

Contactless Respiration and Heart Rate Doppler Extraction — High-precision phase-demodulated radar extracting 0.1 mm chest breathing displacements and ballistic heartbeats from 3 meters away.
In-Home Elderly Fall Detection and Posture Classification — Privacy-preserving room radar identifying sudden elderly fall events without intrusive optical video cameras.
Sub-Milliwatt Medical RF Exposure and SAR Compliance — Ultra-low power radar sensing architectures delivering clinical diagnostic accuracy while operating far below international radiation exposure thresholds.
