MICRO NIDDLE PROBE DEVICE FOR MEASURING STATE OF SAP FLOW

摘要

The present invention discloses a microneedle probe. The present invention, at least a part of the substrate can be inserted into the plant; A pair of metal electrode layers spaced apart from each other on the substrate; A resistance module electrically connecting a pair of metal electrode plates; A power supply for heating the resistance module by applying a current; And a processor capable of measuring the flow state of the sap on the basis of detection information that can be detected as heat exchange between the resistance module and the sap flowing in the plant is performed.
