对关键植物生理参数的活体监测将是精准农业的关键推动因素。在这里，提出了一种基于仿生纺织品的生物传感器，它可以直接插入植物组织：该设备能够在体内和实时地监测植物汁液中溶质含量的变化。即使在连续运行六周后，生物传感器对植物的形态也没有检测到的影响。对生长中的番茄植株的汁液电解质浓度的连续监测揭示了昼夜变化的模式。该生物传感器具有检测非生物胁迫迹象的潜力，因此可能被开发为研究植物生理和提高番茄生长可持续性的有力工具。此外，它还可以持续地传达植物的健康状况，从而潜在地推动智慧农业框架下的整个农场管理。
The in vivo monitoring of key plant physiology parameters will be a key enabler of precision farming. Here, a biomimetic textile-based biosensor, which can be inserted directly into plant tissue is presented: the device is able to monitor, in vivo and in real time, variations in the solute content of the plant sap. The biosensor has no detectable effect on the plant's morphology even after six weeks of continuous operation. The continuous monitoring of the sap electrolyte concentration in a growing tomato plant revealed a circadian pattern of variation. The biosensor has the potential to detect the signs of abiotic stress, and therefore might be exploited as a powerful tool to study plant physiology and to increase tomato growth sustainability. Also, it can continuously communicate the plant health status, thus potentially driving the whole farm management in the frame of smart agriculture.
