Wearable medical device
A wearable cardiovascular sensing platform, in development, with a smart ring as the initial product form factor. It captures cardiovascular-related physiological signals from the periphery using a circular array of electrodes.
- Vascular Impedance Mapping (VIM) electrical sensing rather than optical PPG
- Circular multi-sensor electrode architecture around the finger
- Smart ring form factor as the initial product pathway
- US patent for VIM allowed by the USPTO in February 2026
- Pilot study in 37 volunteers showing correlation with cuff-based blood pressure
- FDA 510(k) submission targeted for Q1 2028
Built for
Consumers and, following regulatory clearance, clinicians monitoring cardiovascular health and hypertension; commercially the assets are positioned for acquisition or licensing by larger medical device and health technology buyers.
