Design and Validation of a Compact Sensor for Peripheral Pulse Waveform Capture

A low-cost compact peripheral pulse sensor captured pulse waveform morphology with reliable beat-to-beat tracking across vascular-tree sites, preserving temporal trends despite feature offsets.

• Why it matters: Multi-site peripheral pulse monitoring can reveal cardiovascular health, but existing hardware often adds intrusion at measurement points.
• What they did: The team built a compact sensor and validated it with in-vitro benchtop tests and a pilot in-vivo clinical study, comparing its waveforms to invasive arterial pressure waveforms.
• The result: While calculated feature offsets were present, fundamental temporal trends and cardiac cycle profiles were preserved, supporting scalable multi-site pulse monitoring for cardiovascular risk screening.
