人体脉搏信号含有重要且有用的生理信息，对于心血管疾病的辅助诊断。在此，报道了一种基于压热传导的可穿戴脉搏传感器，使用结构化银颗粒增强聚二甲基硅氧烷（PDMS）膜来监测径向动脉脉搏波。通过调整结构材料的气隙体积分数和银粒子体积分数，对结构化银粒子增强PDMS膜进行优化设计，以满足脉冲检测对灵敏度、线性度和有效预载测量范围的特定要求。该传感器灵敏度高，在预载测量范围内线性度好，可检测不同年龄段受试者在不同接触压力下的浅（Fu）、中（Zhong）、深（Chen）等细微脉搏波形。所开发的脉冲装置为家庭护理脉冲监测提供了一种有前景的方法。
Human pulse signals contain important and useful physiological information for the auxiliary diagnosis of cardiovascular disease. Here, a wearable pulse sensor based on piezo-thermic transduction is reported using a structured silver-particle reinforced polydimethylsiloxane (PDMS) membrane, for monitoring radial arterial pulse waves. The structured silver-particle reinforced PDMS membrane is optimally designed to meet the specific requirements on sensitivity, linearity, and effective preload measuring range for pulse detection by adjusting the air gap volume fraction and silver particle volume fraction of the structured material. The sensor is endowed with high sensitivity, good linearity in preload measuring range, allowing to detect the subtle pulse waveforms of subjects at different ages under different contact pressures, such as superficial (Fu), medium (Zhong) and deep (Chen). The developed pulse device provides a promising approach for homecare pulse monitoring.
