“…Our group routinely works on research involving screen-printed and microneedle-structured electrochemical sensors that are wearable to the plant and provide in situ and continuous measurements of plant health. We have developed a multiplexed, bioagent-free, three-electrode-based electrochemical sensor, which was screen-printed on a flexible polyimide substrate to measure the salicylic acid (SA) levels directly in plant leaves [ 22 ]. The working electrode was modified with a composite of copper-based metal-organic framework that selectively oxidized SA.…”

Plant-microbe interactions are critical for ecosystem functioning and driving rhizosphere processes. To fully understand the communication pathways between plants and rhizosphere microbes, it is crucial to measure the numerous processes that occur in the plant and the rhizosphere. The present review first provides an overview of how plants interact with their surrounding microbial communities, and in turn, are affected by them. Next, different optical biosensing technologies that elucidate the plant-microbe interactions and provide pathogenic detection are summarized. Currently, most of the biosensors used for detecting plant parameters or microbial communities in soil are centered around genetically encoded optical and electrochemical biosensors that are often not suitable for field applications. Such sensors require substantial effort and cost to develop and have their limitations. With a particular focus on the detection of root exudates and phytohormones under biotic and abiotic stress conditions, novel low-cost and in-situ biosensors must become available to plant scientists.

“…The combined exible patch carrying the strain and pressure sensors was wrapped around the stem. A micron scale (10 µm) hole was punched on the leaf so that sap from the vascular bundle could reach the sensor surface for SA detection [45] .…”

“…Figures 1b-c show the placement of developed sensors on the back of the leaf and around the stem. Several reports published in the literature demonstrate that when a thin adhesive tape is used to attach the sensor at the back of the leaf, an air gap is created between the sensor and the leaf surface, thereby allowing transpiration to occur without any interference [36,37,45] . We developed a voltage divider circuit to measure the resistance variations of the temperature (T), relative humidity (RH), pressure (P), and strain sensors, and a potentiostat circuit capable of conducting cyclic voltammetry on the ethylene (ET) sensor.…”

“…Although exible electrochemical sensors have been reported in the literature for monitoring phytohormones [44][45][46][47] , the research eld is still at its infancy and little to no research has been conducted on developing an integrated hybrid sensing system for real-time quanti cation of volatile and liquid phytohormones and VPD levels along with the radial growth of stem for early diagnosis of crop stress. This work reports the rst-of-itskind integrated, exible, and multiparametric sensor suite that enables continuous and non-destructive monitoring of a plant's physiology with spatiotemporal delity.…”

This work reports a first-of-its-kind hybrid wearable physicochemical sensor suite that we call PlantFit for simultaneous measurement of two key phytohormones, salicylic acid, and ethylene, along with vapor pressure deficit and radial growth of stem in live plants. The sensors are developed using a low-cost and roll-to-roll screen printing technology. A single integrated flexible patch that contains temperature, humidity, salicylic acid, and ethylene sensors, is installed on the leaves of live plants. The strain sensor with in-built pressure correction capability is wrapped around the plant stem to provide pressure-compensated stem diameter measurements. The sensors provide real-time information on plant health under different amounts of water stress conditions. The sensor suite is installed on bell pepper plants for 40 days and measurements of salicylic acid, ethylene, temperature, humidity, and stem diameter are recorded daily. In addition, sensors are installed on different parts of the same plant to investigate the spatiotemporal dynamics of water transport and phytohormone responses. Subsequent correlation and principal component analyses demonstrate the strong association between hormone levels, vapor pressure deficit, and water transport in the plant. Our findings suggest that the mass deployment of PlantFit in agricultural settings will aid growers in detecting water stress/deficiency early and in implementing early intervention measures to reduce stress-induced yield decline.
