In this paper, the novel concept of using heat flux sensors (HFS) to measure arterial pulse on the skin surface is validated. The heat flux (HF) signal is compared with simultaneously measured electrocardiogram (ECG) and photoplethysmography (PPG) signals during both rest and initial recovery from exercise. It is found that the waveform measured with the HF sensor above the radial artery has similar shape to PPG and demonstrates a clear temporal alignment between the HF pulse waves and both the PPG and ECG signals. Further, it is shown that HF measurement can be used to consistently track the arterial pulse at varying skin-to-ambient temperature gradients.

Validity of the Wrist-Worn Polar Vantage V2 to Measure Heart Rate and Heart Rate Variability at Rest
Nuuttila, Olli-Pekka; Korhonen, Elisa; Laukkanen, Jari; Kyröläinen, Heikki (MDPI AG, 2022)Heart rate (HR) and heart rate variability (HRV) can be monitored with wearable devices throughout the day. Resting HRV in particular, reflecting cardiac parasympathetic activity, has been proposed to be a useful marker ... -
