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

Peripheral pulse waveforms captured across different sites of the vascular tree provide valuable insights into cardiovascular health. This study presents a low-cost compact sensor designed to minimize intrusion at the measurement site while capturing the pulse waveform. The sensor performance was characterized and evaluated through both in-vitro benchtop experiments and a pilot in-vivo clinical study against invasive arterial pressure waveforms. The proposed sensor was able to capture pulse waveform morphology with reliable beat to beat tracking. Although offsets were present in the calculated
