Title:
RAIN SENSOR AND WIPER DRIVING APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2016/144054
Kind Code:
A1
Abstract:
A rain sensor according to an embodiment comprises: a substrate; a sensing electrode on a first surface of the substrate; a reaction layer which is formed on the first surface of the substrate and covers the top surface of the substrate and the sensing electrode; a driving unit electrically connected to the sensing electrode formed on the first surface of the substrate, for processing sensing signals transmitted via the sensing electrode; and a protection layer formed to surround the driving unit, wherein the reaction layer has an impedance value which varies according to a change in at least one of the force and dielectric constant caused by rainfall, and the sensing electrode transmits the sensing signals with regard to the variation in the impedance value of the reaction layer.
