摘要

目的:光敏血压计(PPG)作为一种无创方法,已在智能设备中广泛普及,可用于无袖带血压(BP)测量。然而,基于 PPG 的设备的准确性往往受到运动伪影、部位变化和接触力(CF)不一致的影响。本研究旨在调查 CF 变化对 PPG 信号的影响。方法:为了应对这些挑战,我们提出了一种新颖的方法,将多通道 PPG 阵列与 CF 调节集成在可穿戴腕带中。该平台可在监测 CF 的同时,实现区域 PPG/BP 分布的可视化。此外,我们的研究还探讨了伸腕时 PPG 波形特征与 CF 之间的关系。研究结果研究结果表明,根据 PPG 交流脉搏波的二阶导数峰计算得出的 PPG 幅值(PPGA)和 b/a 比值对 CF 变化的反应不一致。值得注意的是,归一化 PPG 和翻转 CF 之间的形状相关系数为 0.65069,这揭示了姿势变化对 PPG 测量的影响。结论:拟议的平台有望减轻 CF 和空间定位对 PPG 的影响,从而提高测量精度,并为持续高血压管理提供一种新的声调动脉造影 (TAG) 活动成像方法。

A multi-channel photoplethysmography array with contact-force regulation for tonoarteriographic imaging
Aim: Photoplethysmography (PPG) has gained widespread popularity as a non-invasive method for potential cuff-less blood pressure (BP) measurement in smart devices. However, the accuracy of PPG-based devices is often hindered by motion artifacts, site variability, and inconsistent contact force (CF). This study aims to investigate the influence of CF variations on PPG signals. Methods: To address these challenges, we present a novel approach involving a multi-channel PPG array integrated with CF regulation in the form of a wearable wristband. This platform enables the visualization of regional PPG/BP distribution while simultaneously monitoring CF. Moreover, our research explored the relationship between PPG waveform characteristics and CF during wrist extension. Results: The results of this study reveal that the PPG amplitude (PPGA) and the b/a ratios, computed from the second derivative peaks of the PPG AC pulse wave, exhibit inconsistency in reaction to CF variations. Notably, a shape correlation coefficient of 0.65069 between normalized PPG and flipped CF sheds light on how changes in posture affect PPG measurements. Conclusions: The proposed platform shows promise in mitigating the effects of CF and spatial positioning on PPG, thereby improving measurement precision and offering a novel approach to image tonoarteriographic (TAG) activities for continuous hypertension management.
