Micro Niddle Probe using Minimally Invasive Technologyfor Measuring Sap Flow

摘要

The present invention relates to a microneedle probe device for measuring the sap flow of a plant by using a minimally invasive technique. The microneedle probe device for measuring the sap flow of a plant by using a minimally invasive technique, according to the present invention, comprises: a pattern layer having a connection pattern for connection to an external power source and a heating pattern capable of generating heat by receiving a current from the external power source; and a base substrate having the pattern layer formed on the surface thereof and having a thickness or width of micrometer units. The base substrate has a structure in which a certain portion thereof is insertable into the plant, and a portion making contact with the heating pattern of the pattern layer can be formed of a material having thermal conductivity lower than that of a silicon substrate material. Thus, the present invention provides the microneedle probe device for measuring the sap flow of a plant by using a minimally invasive technique, which can prevent measurement errors and breakage due to heat loss by forming the substrate for measuring the sap flow, which is inserted into the plant and to which the minimally invasive technique is applied, with the material having lower thermal conductivity and lower brittleness than the silicon substrate material and can improve reliability by forming a heating body with a material effective in a precise measurement technique.
