Technology connects care. AI interprets the pulse.
Fingertip sensing, AI waveform analysis and app-based tracking bring professional care from clinical settings into everyday life.
From measurement to treatment, gaps in hypertension care remain.
More than a billion people worldwide live with hypertension. Many remain above their blood pressure targets even with treatment, leaving them at continued risk of stroke, heart disease and premature death.
For decades, routine blood pressure monitoring has centered on cuff-based systolic and diastolic readings. Yet a single reading captures only one moment, and two numbers cannot fully describe pulse waveform shape or its changes. Understanding cardiovascular health calls for a broader view and ongoing tracking.

FROM SENSING TO ANALYSIS
From optical sensing to AI. The science of fingertip measurement.
Optical sensing captures fingertip photoplethysmography (PPG) signals. Signal quality control and AI waveform analysis then estimate the arterial blood pressure waveform, showing pressure changes throughout the cardiac cycle.
Optical sensing
Dual-wavelength optical sensing
Red and infrared light capture fingertip pulse waves. A stable optical sensor and ambient-light rejection reduce interference from external light sources, preserving waveform detail and variation.
- Japanese-made optical module
- Ambient-light suppression
Signal processing
On-device filtering and quality assessment
On-device filtering and signal-quality assessment reduce noise and select pulse signals that meet quality thresholds, providing reliable input for subsequent AI analysis.
