技術說明

本發明提供一種氣體感測器，包含基板、複數彼此相間隔的絕緣塊、上電極單元、感測層，及電位耦合層。該基板包括一可導電的上表面，該等絕緣塊設於該上表面，該上電極單元包括複數個分別對應設於該等絕緣塊的表面且彼此間隔設置的電極部，該感測層覆蓋該等電極部、該等絕緣塊，及該基板，用以感測預定的待測氣體分子，該電位耦合層由有機導電高分子所組成，且覆蓋於該感測層上，並可使待感測的該氣體分子通過。此外，本發明還提供另外一種態樣的氣體感測器，一下電極設於該感測層，該上電極單元設於該感測層上，且該電位耦合層覆蓋該上電極單元。 This invention provides a gas sensor that includes a substrate, a plurality of isolated insulators, a top electrode unit, a sensing layer, and a voltage coupling layer. The substrate includes a conductive surface. The insulators are disposed on the conductive surface. The top electrode unit includes a plurality of separated electrode portions which are disposed on the surfaces of those insulators. The sensing layer covers the electrode portions, the insulators and the substrate, and is used for detecting specific gas molecular. The voltage coupling layer covers the sensing layer and is made of conductive polymer that is penetrable for the specific gas molecular. This invention also provides anther gas sensor that a bottom electrode is disposed on the sensing layer, the top electrode unit is disposed on the sensing layer, and the voltage coupling covers the top electrode unit.
