Yihu is an AI-powered care intelligence platform designed to improve long-term care for patients with Alzheimer’s disease, Parkinson’s disease, stroke, and other chronic conditions. The system combines contactless mmWave radar monitoring with AI voice documentation to automatically capture patient status, structure care records, and detect potential risks in real time. By reducing paperwork and providing timely decision support, Yihu helps caregivers work more efficiently and improves care quality. The platform is delivered to nursing homes and rehabilitation facilities through a per-bed subscription model, with future expansion to home-based care.
