Biospectal

Biospectal's OptiBP app measures blood pressure using a fingertip and smartphone camera. It claims medical device compliance by translating camera signals into BP estimates, offering a cuff-free consumer option, though authorities still regard 24-hour ambulatory monitoring as gold standard.

Biospectal integrates CSEM’s oBPM technology into smartphones, enabling cuffless blood pressure monitoring via photoplethysmographic signals. The system achieves a mean error below 4.0 mmHg and correlations up to 0.94 across multiple body locations, underscoring its role in health tech.
