MICRONEEDLE, MICRONEEDLE MANUFACTURING METHOD, MICRONEEDLE SENSOR, AND MICRONEEDLE SENSOR MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To acquire data on a biological tissue, etc. electrically or electrochemically in consideration of biocompatibility of a quality of material, fragility against contact, electric conductivity, electrochemical stability, and low manufacturing cost.SOLUTION: A microneedle includes an insulator having a first surface that comes in close contact with an object and a second surface which is a rear surface of the first surface, a plurality of conductive projection parts provided to the insulator, whose tips are exposed from the first surface of the insulator, and a carbon continuous film with a thickness of 1 μm or more, which coats the projection parts. A microneedle sensor is applied on a surface of a living body or a substance originating from a living body, and data on a tissue of the living body or the substance originating from the living body can be electrically or electrochemically acquired with a high degree of reliability.SELECTED DRAWING: Figure 1
