Hotter summers caused by global warming and increased workload and duration are endangering the health of farmworkers, a high-risk population for heat-related illness (HRI), and deaths. Although prior studies using wearable sensors show the feasibility of employing field-collected data for HRI monitoring, existing devices still have limitations, such as data loss from motion artifacts, device discomfort from rigid electronics, difficulties with administering ingestible sensors, and low temporal resolution. Here, this paper introduces a wireless, wearable bioelectronic system with functionalities for continuous monitoring of skin temperature, electrocardiograms (ECG), heart rates (HR), and activities, configured in a single integrated package. Advanced nanomanufacturing based on laser machining allows rapid device fabrication and direct incorporation of sensors with a highly breathable substrate, allowing for managing excessive sweating and multimodal stresses. To validate the device's performance in agricultural settings, the device is applied to multiple farmworkers at various operations, including fernery, nursery, and crop. The accurate data recording, including high-fidelity ECG (signal-to-noise ratio: >20 dB), accurate HR (r = 0.89, r = 0.65 in linear correlation), and reliable temperature/activity, confirms the device's capability for multiparameter health monitoring of farmworkers.
全球变暖导致的夏季炎热以及工作负荷和时长的增加，正危及从事农业工作的高危热相关疾病（HRI）人群的健康，并导致死亡。尽管先前使用可穿戴传感器的研究表明，采用现场采集的数据进行 HRI 监测具有可行性，但现有设备仍存在局限性，例如运动伪影导致的数据丢失、刚性电子设备导致的设备不适、内置传感器的管理困难以及时间分辨率低等问题。本文引入了一种无线可穿戴生物电子系统，具有连续监测皮肤温度、心电图（ECG）、心率（HR）和活动的功能，这些功能集成在单个封装中。基于激光加工的先进纳米制造技术允许快速制造设备，并直接将传感器与高度透气的基底集成，从而可以管理过度出汗和多模态压力。为了验证该设备在农业环境中的性能，该设备应用于多个在不同操作中的农场工人，包括蕨类植物种植、苗圃和作物种植。准确的数据记录，包括高保真 ECG（信噪比：>20dB）、准确的 HR（线性相关中的 r = 0.89，r = 0.65）和可靠的温度/活动，证实了该设备对农场工人进行多参数健康监测的能力。
