The real-time monitoring of hydrogen peroxide (HO) is significant for understanding the working mechanism of signal molecules, breeding for stress tolerance, and diagnosing plant health. However, it remains a challenge to realize real-time monitoring of the dynamic HO level in plants. Here, we report an implantable and self-powered sensing system for the continuous monitoring of HO level in plants. A photovoltaic (PV) module is integrated into a sensing system to collect sunlight or artificial light in the planting environment in order to continuously power an implantable microsensor. The transmission process of the HO signal was monitored and analyzed , and the time and concentration specificity of the HO signal for abiotic stress were resolved. This implantable system provides a promising analysis tool for key signal molecules in plants and might be extended to the real-time monitoring of signaling molecules in other crops.

用于植物体内动态 H2O2 水平监测的植入式自供电传感系统

过氧化氢（H2O）的实时监测对于了解信号分子的工作机制、耐逆性育种和诊断植物健康具有重要意义。然而，实现植物中动态H2O水平的实时监测仍然是一个挑战。在这里，我们报告了一种可植入的自供电传感系统，用于连续监测植物中 H2O 水平。光伏 (PV) 模块集成到传感系统中，用于收集种植环境中的阳光或人造光，以便为植入式微传感器持续供电。对HO信号的传递过程进行监测和分析，解决了HO信号对非生物胁迫的时间和浓度特异性。这种植入式系统为植物中的关键信号分子提供了一种有前途的分析工具，并可能扩展到其他作物中信号分子的实时监测。
