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.

AI analysis
AI blood pressure waveform analysis
Personalized deep learning models estimate arterial blood pressure waveforms from optical pulse signals and derive 32 cardiovascular indicators, revealing physiological information beyond systolic and diastolic pressure.
- Personalized deep learning model
- 32 cardiovascular metrics
CLINICAL VALIDATION
Innovation starts with technology. Trust is built on evidence.
Measurements from 111 participants at Hualien Tzu Chi Hospital were compared with a mercury sphygmomanometer to assess blood pressure measurement performance against ISO 81060-2:2018.
