“…[24] Another recently developed flexible sensor has been reported for monitoring illumination, RH, and temperature on the leaf. [25] Despite the development of several plant sensors, [26][27][28][29][30][31] existing on-leaf RH and temperature sensors are limited to measurements in the greenhouse over relatively short periods of time; the performances of these sensors under field conditions have not been studied.…”

This work presents a wearable sensor for real‐time on‐leaf monitoring of relative humidity (RH), temperature, and vapor‐pressure deficit (VPD) of plants in both controlled environments and under field conditions. This sensor is flexible and conformable to the leaf surface. By integrating a graphene‐based RH sensing element and a gold‐based thin‐film thermistor on a polyimide sheet, the sensor allows accurate and continuous determination of VPD at the leaf surface, thereby providing information on plant transpiration. A greenhouse experiment validates the ability of the sensor to continuously and simultaneously monitor both the leaf RH and temperature of maize plants over more than 2 weeks. The sensor output also demonstrates the influences of light and irrigation on maize transpiration. Uniquely, by attaching multiple sensors onto different locations of a plant, it is possible to estimate the time required for water to be transported from the roots to each of the measured leaves along the stalk, as well as longitudinally from one position on a leaf toward the leaf tip. Sensors are also deployed in crop production fields where they demonstrate the ability to detect difference in transpiration between fertilized and unfertilized maize plants.

“…The potential applications of tattoo-like wearable plant sensors extend beyond their current capabilities of measuring relative water content, temperature, and biopotential levels. By incorporating appropriate sensing elements designed to monitor physical (e.g., strain and light exposure) [58,59] and biochemical parameters (e.g., nutrient levels, virus presence, and volatile organic compound emissions), [21,[60][61][62] these devices could provide a holistic view of plant health, growth dynamics, and responses to environmental stresses. Such comprehensive monitoring could significantly improve agricultural practices by enhancing fertilization, irrigation, and pest control strategies.…”

This study presents a wearable plant tattoo sensor array designed for continuous monitoring of leaf temperature, relative water content, and biopotential. Current plant wearable sensor technologies often require relatively bulky substrates for sensor support and adhesives for leaf attachment, which potentially can hinder plant growth and affect long‐term measurements. The multifunctional tattoo sensor array overcomes these issues by adhering directly to the leaf surface without the need for additional supporting structures or glues. This array includes a biopotential electrode, a resistive temperature sensor, and an impedimetric water content sensor, all constructed using laminated gold‐on‐polymer thin‐film patterns. Due to their mechanical flexibility, stretchability, and conformability, the sensors can seamlessly attach to leaves via van der Waals force. Performances of these sensors are evaluated to explore plant responses under diverse growth environments. This sensor array is capable of both short‐term and long‐term monitoring, offering continuous data and detailed insights into plant physiological responses to various stress conditions.

“…As plant growth causes changes in strain, materials developed for wearable sensors for plant growth should be strain‐sensitive. This applies to both substrates, for example, PDMS, [ 45 ] latex, [ 46 ] and Ecoflex [ 47 ] and sensing layers such as the chitosan‐based composite [ 48 ] of a wearable sensor.…”

“…Similar conventional laboratory‐based techniques have been employed for the collection of sensor data that may not be adequate for point‐of‐use plant monitoring and are not conducive to real‐time monitoring. [ 23,25–28,32,41a,47,48,51 ] On the other hand, Lee et al. [ 16 ] proposed the inductively coupled functionality of monolithic all‐carbon electronics operating at radio frequency for real‐time sensing of toxic gases wirelessly using a simple LRC passive circuit, highlighting their untethered easy‐to‐use capabilities.…”

Plants provide humankind with a habitable environment, food, and oxygen. Due to changing climate and increasing global population, there is pressure to increase agricultural production while limiting negative impacts on natural ecosystems. Understanding plant physiology and plant‐environment interactions is needed to further sustainable agricultural practices and maintain a green and diverse environment. Early detection of signals characteristic to plant stress can help to design interventions to preserve yield or diversity. Therefore, technology development is important to monitor plant health by measuring a variety of parameters related to the microclimate around plants and plant physiology. This review focuses on state‐of‐the‐art wearable sensors developed for plants.
