To reduce the crop losses associated with biotic and abiotic stresses, novel sensor technologies that can monitor plant health and predict and track plant diseases in real time are required. Plant sensors based on wearable technologies are placed directly on the plant leaf or stem. The health status of the plant is reflected by various biomarkers and microenvironmental parameters, which are converted into electric readouts by the sensors for convenient analysis. Herein, the latest research progress in the field of wearable plant sensors is evaluated, and the sensors are classified according to their individual functions. Moreover, the design principles and working mechanisms of previously reported wearable sensors are analyzed, and the design features adopted to overcome the difficulties associated with precision agriculture are explored. Finally, the challenges and future development prospects in this field are outlined. This review contributes to the growing body of literature on wearable plant sensors, underscoring their critical role in mitigating crop losses through real-time plant health monitoring and disease prediction. Advancements in wearable plant sensors could ultimately revolutionize crop production and sustainability by enabling more precise, efficient, and proactive farming practices.
