However, conventional pulse-amplitude modulation (PAM) fluorometers are primarily designed for point measurements and are not suitable for long-term monitoring while attached to intact leaves. Here, we developed Sensor-PAM, a wearable chlorophyll fluorescence measurement system capable of continuously monitoring photosynthetic dynamics from the abaxial side of a leaf. The system combines a commercially available color sensor with blue LEDs in a compact, low-cost optical design to perform PAM measurements. Chlorophyll fluorescence measured from the abaxial leaf surface showed a strong correlation with conventional adaxial measurements and accurately reflected changes in photosynthetic performance induced by chilling and high-light stress. Measurements obtained using Sensor-PAM also showed good agreement with those from a commercial PAM fluorometer across diverse plant species. Furthermore, the wearable system enabled continuous monitoring of the effective quantum yield of photosystem II [Y(II)] from the same position on the same strawberry leaf for three days under both greenhouse and outdoor conditions, successfully capturing photosynthetic responses to changing irradiance and temperature in real time. These findings establish Sensor-PAM as a wearable platform for continuous chlorophyll fluorescence monitoring, extending conventional PAM fluorometry from point-based measurements to long-term monitoring of photosynthetic dynamics under natural environmental conditions.","连续监测光合性能对于理解植物对波动环境的响应至关重要，在植物生理学、田间表型分析和数字农业中具有重要应用。然而，传统的脉冲振幅调制（PAM）荧光仪主要设计用于单点测量，不适合在附着于完整叶片的情况下进行长期监测。在此，我们开发了Sensor-PAM，一种可穿戴叶绿素荧光测量系统，能够从叶片远轴面连续监测光合动态。该系统将市售颜色传感器与蓝色LED相结合，采用紧凑、低成本的光学设计来执行PAM测量。从叶片远轴面测得的叶绿素荧光与传统近轴面测量结果高度相关，并准确反映了低温胁迫和高光胁迫引起的光合性能变化。使用Sensor-PAM获得的测量结果在不同植物物种中也与商用PAM荧光仪的结果吻合良好。此外，该可穿戴系统能够在温室和户外条件下，对同一片草莓叶片同一位置连续三天监测光系统II有效量子产率[Y(II)]，成功实时捕捉了光合作用对光照和温度变化的响应。这些发现确立了Sensor-PAM作为一种可穿戴叶绿素荧光监测平台，将传统PAM荧光测定从单点测量扩展到自然环境下光合动态的长期监测。",null,"bioRxiv (Cold Spring Harbor Laboratory)","2026-09-17T00:00:00Z","论文",10,false,81,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":13,"relevant":20,"comment":21},18,22,13,1,"可穿戴叶绿素荧光监测系统实现叶片光合动态连续监测，方法新颖、数据扎实，对作物表型与数字农业有实用价值，值得进入每日精选。",[23],{"name":10,"url":6},[25,26,27,28,29],"数字农业","智慧农业","叶绿素荧光","可穿戴传感器","光合表型",0,"10.64898\u002F2026.09.12.751108",{"doi":31,"openalex_id":33,"authors":34,"venue":10,"cited_by_count":30,"oa_url":6,"card":47,"direction":51,"ingested_from":53},"W7213448370",[35,38,41,44],{"name":36,"orcid":37},"Ko‐ichiro Miyamoto","https:\u002F\u002Forcid.org\u002F0000-0001-7889-6714",{"name":39,"orcid":40},"Kentaro Ifuku","https:\u002F\u002Forcid.org\u002F0000-0003-0241-8008",{"name":42,"orcid":43},"Tatsuo Yoshinobu","https:\u002F\u002Forcid.org\u002F0000-0001-7993-716X",{"name":45,"orcid":46},"Kaori Kohzuma","https:\u002F\u002Forcid.org\u002F0000-0003-3899-543X",{"tldr":48,"method":49,"finding":50,"direction":51,"opportunity":52},"开发了可穿戴叶绿素荧光系统Sensor-PAM，实现叶片背面光合动态连续监测。","低成本颜色传感器与蓝光LED集成，进行PAM测量并验证。","背面测量与常规正面测量强相关，可连续三天监测草莓叶片Y(II)动态。","农业遥感与作物表型","可穿戴荧光传感器为田间高通量表型提供新手段，可探索多物种长期监测与数据融合。","openalex","2026-09-17T23:30:29.467723Z"]
