    摘要： A capacitive gas sensor and a method of fabricating the same are provided. The capacitive gas sensor includes an insulating substrate, a metal electrode and a micro thin-film heater wire integrally formed on the same plane of the insulating substrate, and an oxide detection layer coated on the metal electrode and the micro thin-film heater wire. The fabrication method includes depositing a metal layer on an insulating substrate, etching the metal layer so that a metal electrode and a micro thin-film heater wire form an interdigital transducer on the same plane, and forming a nano crystal complex oxide thin film or a complex oxide nano fiber coating layer on the metal electrode and the micro thin-film heater wire as a detecting layer. The capacitive gas sensor can be easily fabricated and can have excellent characteristics such as high sensitivity, high selectivity, high stability, and low power consumption.

    摘要： A gas sensor for detecting environmentally harmful gases is provided. The sensor includes an insulating substrate, a metal electrode formed on the insulating substrate, and a sensing layer formed on the metal electrode and including a semiconductor oxide (Lan+1NinO3n+1(n=1,2,3)) nanofiber. Therefore, a semiconductor oxide (Lan+1NinO3n+1(n=1,2,3)) has an ABO3-type basic crystalline structure and thus is stable in structure, and is a representative material having a nonstoichiometric composition due to oxygen defects. Since the semiconductor oxide has great oxygen defects on its surface, a great change in electrical resistance may be exhibited due to reactive gas adsorption and oxidation/reduction reaction on the oxide surface. Also, a method of fabricating the gas sensor is provided.
