Advances in Plant Wearable Sensors for the Physiological and Biochemical Information of Horticultural Crops

doi:10.11983/CBB25095

Abstract

Abstract: Horticultural plants are of great significance in cultural inheritance, economic development, and ecosystem sustainability. However, the advancement of horticultural practices is hindered by challenges such as climate change, labor shortages, and inefficient resource utilization. Plant information sensing technology provides innovative solutions to these challenges. Among these technologies, plant wearable sensors have emerged as promising tools for monitoring plant physiological and biochemical information due to their high flexibility, extensibility, spatiotemporal resolution, and biocompatibility, and are becoming essential tools for acquiring data on the plants and their growing environments. Nevertheless, a systematic review of wearable sensor applications in horticultural plant research remains lacking. This review focuses on horticultural plant information detection and comprehensively discusses and summarizes plant wearable sensors’ status of research and applications in the following areas: growth monitoring, moisture content detection, stem sap flow analysis, electrical signal acquisition and chemical substance detection. Finally, we propose future development directions to provide references for information detection in horticultural plants.

Key words: horticultural plants, information monitoring, wearable sensors, smart horticulture
