A nondestructive testing device for water content of plant leaves based on planar interdigital electrodes

Abstract

This application relates to the field of detection device technology, and in particular to a non-destructive detection device for plant leaf moisture content based on a planar interdigitated electrode. The device includes a lower clamping body, a lower clamp, an upper clamping body, an upper clamp, and an elastic connection mechanism. The lower clamping body has a lower clamp for supporting the leaf at its front end, and an upper clamping body is located above the lower clamping body. The upper clamp has an upper clamp at its front end, and a detection component for detecting leaf moisture content is located at the bottom of the upper clamp. The detection component includes a planar interdigitated electrode, and a rubber pad is attached to the upper end of the lower clamp. This invention enables the planar interdigitated electrode to make close contact with the leaf surface, quickly acquiring capacitance signals to accurately detect leaf moisture content without damaging the leaf. Simultaneously, the soft rubber pad acts as a buffer during the planar interdigitated electrode detection, preventing physical damage to the leaf during clamping. This ensures both the accuracy and timeliness of the detection data while maintaining the integrity of the leaf sample.
