Researchers describe wearable-style sensors for plants that aim to give farmers real-time information about crop health before visible symptoms appear. The concept builds on human wearable technology, such as smartwatches that continuously measure physiological signals, by applying similar continuous monitoring to plants. The devices are small sensors that can be attached to leaves and stems and are designed to detect early distress signals related to water stress, including distinguishing between drought and salinity stress. Sources also say the wearables can monitor indicators tied to plant growth changes and can help identify issues such as disease or nutrient problems days before farmers would typically notice signs like curling leaves or stunted growth. The sensors are described as operating continuously using power derived from moisture evaporation, enabling ongoing field data collection without frequent recharging. With deployment as a network of sensors across fields, the approach is intended to provide a more direct, plant-focused view of field conditions and support earlier management decisions by farmers based on up-to-date readings.
