671. 柔性PMN-PT超声阵列与无袖带血压监测研究

from 知为谁 · host 知为谁

这项研究介绍了一种柔性超声换能器阵列(UTA),旨在通过皮肤贴合式的可穿戴设备实现连续且无袖带的血压监测。研究人员采用了高性能的PMN-PT压电复合材料,并利用创新的低温共晶焊技术解决了柔性电子制造中易导致材料退化的热损伤问题。该传感器能够精准追踪血管直径的变化,并通过声学信号实时重建收缩压与舒张压波形。实验结果表明,该系统的测量精度已达到临床标准,在远程医疗和点对点健康监测领域具有显著的应用潜力。其轻薄、可拉伸的设计确保了佩戴的舒适性与信号稳定性,为下一代高性能柔性超声医疗设备开辟了新路径。内容来源:https://www.nature.com/articles/s41378-025-01110-2
