Abstract
According to an exemplary embodiment, a microneedle probe device for measuring a sap flow rate of a plant includes: a substrate, of which at least a part is inserted into a plant, and a thickness and a width are microscales; a single metal wire provided on the substrate; a power source, which applies a current to the metal wire for a predetermined time and heats the metal wire; and a processor, which calculates a flow rate of sap through a movement of heat generated in the metal wire according to a flow of the sap within the plant.
