A Sub-Gram Individual Plant Stress Sensor Tag for Smart Farming

📋 论文概要

本文提出了一种0.62g轻量无电池传感器标签，用于持续监测植物应激。通过920MHz无线链路为标签供电，并利用基于异或的多路复用器将pH数据反向散射回链路，实现了单天线同时供电和数据传输，距离达80cm。成功演示了超过30天的活体植物应激监测，为智能农业提供低功耗传感方案。

💡 主要创新点

• 实现亚克级（0.62g）无电池植物应力传感器标签，可连续监测pH值。
• 提出基于异或多路复用器的单天线架构，同时支持无线供电和数据反向散射，通信距离80cm。
• 展示了超过30天的活体植物长期监测，验证了实际农业应用可行性。

California, Los Angeles, CA, Kyushu University, Fukuoka, Japan 1 5 Abstract This paper presents a 0.62g light-weight battery-less sensor tag for continuous monitoring of plant stress. A wireless link at 920MHz powers the tag for in-vivo measuring pH in the plant as a key stress indicator. The pH data are backscattered to the link through an XOR- based multiplexer, enabling a single miniature antenna to establish simultaneous power and data link over 80cm distance. More than 30-days in-vivo plant stress monitoring was successfully demonstrated for future smart farming. This paper presents a 0.62g ultra-light-weight battery-less sensor tag for continuous monitoring of plant stress conditions. A wireless link at 920MHz powers the tag for
