Title
A Cost-Effective, High-Performance, And Bio-Inspired Pulse Sensor For Quantitative Assessment Of Arterial Stiffness
Abstract
In this paper, we aim to develop a novel non-invasive and wearable radial pulse sensor that is of high accuracy, low cost, and high sensitivity. To reach the goal, the ultrasensitive hybrid carbon/polymer-based piezoresistive (HCP) film with high-sensitivity and low thermal-drift is selected, and its miniaturized signal conditioning circuit board is tailor-made. Specifically, inspired by effectively feeling the pulse through the fingertip tactile palpation, by mimicking the fingertip physical structure featuring with the high-performance mechanical sensing properties such as damping and bandwidth filtering, we design the bioinspired pulse sensor in which the HCP sensing film is enveloped by the skin-like or tissue-like soft rubber. The sensor is well calibrated and its sensing performance including accuracy, repeatability, and sensitivity is experimentally validated. The developed sensor has been employed to measure radial pulses and to further determine arterial stiffness or aging by computing the pulse-related critical vital parameters such as augmentation index (AI) and pulse transit time (PTT). The results indicate the arterial stiffness or aging can be quantitatively assessed by our low-cost but high-performance sensor, which is validated by a commercial sensor.
