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.

完全集成的无源无线传感器，具有机电双梯度，用于多功能医疗保健监测


准确、有效和持续地监测压力、湿度和温度对于常规健康评估和专业患者护理至关重要。在本研究中，我们提出了一种完全集成的多参数无源无线传感器 （MWS），它采用机械-电气双梯度结构设计。独特的梯度多孔结构使 MWS 在检测尺寸（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，该传感器的压敏度提高了 2.6 倍，并具有 5 层水分检测能力。通过弥合高精度多参数传感、无线通信和能源管理之间的技术差距，MWS 能够测量多个生理参数，包括呼吸、心动图、湿度和多点温度，提供对受试者生理状态的实时评估。这项工作为护理人员提供了有价值的定量见解，并为个人医疗保健管理的重大进步铺平了道路。
