Abstract

The invention discloses a gas sensor imitating a scorpion comb tooth and a preparation method thereof. The gas sensor imitating a scorpion comb tooth comprises: a round bottom plate, a dome plate connected between the round bottom plate and the dome plate Several vertical plates, the center of the dome plate is provided with a first through hole, and the several vertical plates are arranged radially along the dome plate from the edge of the first through hole to the edge of the dome plate; A bionic comb-tooth-shaped gas sensor is arranged between two adjacent vertical plates, and the bionic comb-tooth-shaped gas sensor is inclined from bottom to top to the center of the dome plate. Because all the bionic comb-tooth-shaped gas sensors converge upward together into a truncated cone and point to the first circular hole. The structure of the gas sensor imitating scorpion comb teeth can not only increase the contact area between the gas sensor and the volatile chemical substances, but also prolong the residence time of the volatile chemical substances, so that the resistance of the gas sensor can reach a faster and larger The change improves the sensitivity of the gas sensor.

Description

technical field [0001] The invention relates to the technical field of gas sensing, in particular to a gas sensing sensor imitating scorpion comb teeth and a preparation method thereof. Background technique [0002] In today's information age, sensing and control technology, communication technology and computer technology constitute the three pillars of modern information technology. Some people vividly compare computer technology to the "brain" of the information world, sensor technology to the "five senses", and gas sensing technology to the "nose" in the "five senses". As an important means of accurate acquisition and precise detection of chemical substance information, gas-sensing sensing technology has not only received widespread attention from all countries, but also has become one of the fastest-growing technologies. In the prior art, the structure of the gas sensor is simple, and the sensitivity of the gas sensor is low. [0003] Therefore, the prior art still ne...
