Flexible screen-printed electrodes (FSPEs) are electrochemical sensors made by printing conductive ink onto a flexible substrate such as polyester or polyimide. FSPEs can be programmed to detect a wide range of analytes, such as ions, gases, and biomolecules, making them useful sensors for a wide range of applications. They're commonly made utilizing screen-printing procedures, which entail transferring conductive ink via a mesh screen onto a flexible substrate. After drying and curing, the ink forms a durable conductive layer that can be utilized as the working electrode in an electrochemical sensor. To improve selectivity and sensitivity to certain analytes, FSPEs can be modified with specific sensing materials or coatings. FSPEs can be used to monitor plant nutrient levels in a variety of ways, including in situ sensing and distant monitoring. In situ sensing is the use of a handheld or portable electrochemical sensor to directly assess nutrient levels in soil or plant tissue. The usage of FSPE-based sensors that are incorporated into a wireless network and can offer real-time data on plant nutrient levels is used for remote monitoring. FSPEs provide various advantages over standard nutrient monitoring systems, including low cost, portability, and ease of use. FSPEs can also identify essential plant nutrients quickly and accurately, allowing for prompt action to treat nutrient deficits or excesses. However, FSPEs have several limitations, such as selectivity and sensitivity to specific analytes. To improve their selectivity and sensitivity to specific plant nutrients, FSPEs may require specific coatings or modifications. Furthermore, FSPEs may necessitate regular calibration to maintain accurate and repeatable results.
