Abstract : The emerging interest in precision farming among scientific communities is rapidly evolving due to increasing food demand and abating climatic conditions. Alleviating plant stress to ensure crop health is a major concern among farmers. Plant stress, typically abiotic stress, is known to cause major losses in agriculture worldwide. This paper reviews the wearable sensors designed for ambient monitoring of abiotic stress responses generated in plants. Various stress types encountered in plants along with their classification, the parameters taken into consideration for microclimate monitoring, and their physiological effects have been discussed. Different types of wearable plant sensors for detecting parameters such as temperature, humidity, light, nutrients, phytohormones, volatile organic compounds, glucose, and strain are considered here. The wearable sensors designed for each parameter, the materials utilized, and sensor metrics have been provided. Sensor responses when subjected to real-time monitoring in fields have also been considered. The challenges faced and future research possibilities are also identified.
