nityCare is developing a smart wearable system that combines RF-based activity tracking with ECG monitoring to support cardiac assessment and psychiatric biofeedback. The system includes a wristband-based activity device, an ECG patch, and a digital platform for real-time monitoring, cloud-based data storage, alerts, and clinical review. Its stress-specific HRV approach is designed to separate exertion-related cardiac changes from non-metabolic stress responses, giving clinicians and patients a clearer view of stress physiology. By connecting activity, arrhythmia detection, and mental health biofeedback in one platform, UnityCare is building a wearable system for more continuous and personalized health monitoring.
