Abstract
A microneedle probe for measuring a sap flow in a plant is disclosed, the microneedle probe including: a substrate; and a sensor unit which is installed on the substrate, generates heat, and measures a temperature that changes in accordance with a sap flow.
Claims18
A microneedle probe configured to be inserted into a xylem of a plant to measure a flow of sap in the xylem, the microneedle probe comprising:
- a substrate extending along a longitudinal axis between a first end and a second end, the substrate defining an insertion portion that is configured to be inserted into the xylem of the plant when the microneedle probe is inserted into the xylem of the plant;
- a sensor unit disposed on the insertion portion of the substrate and configured to measure the flow of sap;
- wherein the sensor unit includes two temperature measuring sensors which are separated from each other in a direction which is perpendicular to the longitudinal axis of the substrate, and a heater which is positioned between the two temperature measuring sensors.
A microneedle probe for measuring a sap flow in a plant, the microneedle probe comprising:
- a substrate which is inserted into the plant and has a microscale in a thickness direction and a width direction;
- and
- a sensor unit which is installed on a portion of the substrate inserted into the plant for measuring a sap flow;
- wherein the sensor unit includes two temperature measuring sensors which are separated from each other in a direction which is perpendicular to a longitudinal direction of the substrate, and a heater which is positioned between the two temperature measuring sensors.
