Vision
Why VitaRay?
Falls are a leading cause of injury and long-term disability among elderly and high-risk patients, particularly in unsupervised or home-based care settings. To address this challenge, I developed VitaRay, a non-intrusive fall-detection and vital-sign monitoring system based on millimeter-wave (mmWave) radar technology. Unlike wearable or camera-based solutions, VitaRay requires no user interaction, does not capture video, and preserves patient privacy while operating continuously in the background. Performance testing shows that VitaRay achieves fall-detection accuracy and vital-sign monitoring performance comparable to toptier industry benchmarks. Through custom circuit-board design and algorithm optimization, the system reduces processing requirements by approximately 60–80%, significantly lowering overall cost compared to commercial alternatives. A diversified supply chain further improves scalability and resilience.
