Exploration of the Plant World: Application and Innovation of Plant-Wearable Sensors for Real-Time Detection

wireless connections with smart devices. This facilitates user management and monitoring, which can contribute to the development of intelligent agriculture with high planting efficiency and sustainability. This review summarizes the design principles, manufacturing methods, characteristics, and feasibility of plant-wearable sensors based on their functions, including plant-phenotype sensors (e.g., hormones and nutrients), plant-growth-environment sensors (e.g., surrounding humidity), and plant stress sensors (e.g., pesticides, volatile organic compounds, and environmental stress). It also explores the challenges and development prospects in this field, providing valuable insights into the future application of wearable sensors to effectively optimize the plant growth status for crop yield and quality.
