This work investigates the time difference between epidermal pressure pulse and PPG signal over the radial artery. 8 healthy subjects including 4 females participated in the experiment with their PPG signals and epidermal pressure pulses recorded at wrist simultaneously by a multi-modal pulse sensing patch. The arrival times of two signals are marked by three different characteristic points. The result shows that there is a significant delay between the peaks of epidermal pressure pulse and PPG signal.



The authors would also like to thank the student volunteers for their participation in the experiment. This work was in part supported by the Guangdong Innovative Research Team fund in China and the HKSAR Innovation and Technology Commission (ITC) Innovation and Technology Fund (ITF), ITS/111/14.
