Abstract

Provided is a sensor comprising a non-conductive substrate; and a conductive layer electronically printed on one side of the substrate, wherein the conductive layer comprises: an antenna pattern for transmitting and receiving a radio signal with an external device; a sensing electrode connected to the antenna pattern via a circular wiring for sensing an impedance change due to contact with a sensing target material; and a coating electrode stacked on the sensing electrode for removing an occurrence of noise of the impedance change. Accordingly, the present invention solves the problem of a sensor, in the form of a terminal, not being compact and the problem of high manufacturing costs and low manufacturing quality of a sensor manufactured using a deposition method in order to replace such sensor with a sensor manufactured by a printing method, and solves a corrosion problem of a sensing electrode, a durability problem, etc. that may occur in the sensor of the printing method.
