Abstract

Accurate, effective, and continuous monitoring of pressure, moisture, and temperature is essential for routine health assessments and professional patient care. In this study, we present a fully integrated multiparameter passive wireless sensor (MWS) that employs a mechanical–electrical dual-gradient structure design. The unique gradient porous structure endows the MWS with significant advantages in terms of detection dimensions (pressure, moisture, and temperature), sensitivity, and stability. Compared to single mechanical gradient designs, the sensor demonstrates 2.6 times higher pressure sensitivity and a 5-tier moisture detection capability. By bridging the technology gap between high-precision multiparameter sensing, wireless communication, and energy management, the MWS is capable of measuring multiple physiological parameters, including breath, ballistocardiograph, moisture, and temperature at multiple points, providing real-time assessments of the physiological state of the subjects. This work offers valuable quantitative insights for caregivers and paves the way for significant advancements in personal healthcare management.

用于多功能医疗监控的机械-电气双梯度全集成无源无线传感器

对压力、湿度和温度进行准确、有效和连续的监测对于常规健康评估和专业病人护理至关重要。在这项研究中，我们提出了一种完全集成的多参数无源无线传感器（MWS），它采用了机械-电气双梯度结构设计。独特的多孔梯度结构使 MWS 在检测维度（压力、湿度和温度）、灵敏度和稳定性方面具有显著优势。与单一机械梯度设计相比，该传感器的压力灵敏度提高了 2.6 倍，并具有 5 级湿度检测能力。通过弥合高精度多参数传感、无线通信和能量管理之间的技术差距，MWS 能够在多个点测量多种生理参数，包括呼吸、心球图、湿度和温度，从而对受试者的生理状态进行实时评估。这项工作为护理人员提供了宝贵的量化见解，并为个人医疗保健管理的重大进步铺平了道路。
