Cohabiting Plant-Wearable Sensor In Situ Monitors Water Transport in Plant

Yangfan Chai et al.

Summary: This study presents a flexible electronic sensor that can coexist harmlessly with plants and continuously monitor the stem sap flow, contributing to plant health analysis, water consumption, and nutrient distribution. The sensor, with its light, soft, air/water/light-permeable design, enables continuous and non-destructive plant monitoring, showing great potential in phenotyping research. Additionally, the real-time investigation on watermelon stem flow revealed a previously unknown day/night shift pattern of water allocation between fruit and its adjacent branch.
