Abstract

The invention provides a gas sensor based on swelling dynamic response and a preparation method thereof. The gas sensor comprises a substrate, a conductive layer arranged on the substrate and an electrode arranged on the conductive layer; the substrate comprises a first composite layer and a second composite layer which are combined with each other; the modulus of the second composite layer is greater than that of the first composite layer, and the stress of the second composite layer on the first composite layer is greater than the critical stress of the second composite layer for forming wrinkles when the second composite layer swells organic gas, so that the second composite layer deforms to form wrinkles. The light transmittance of the gas sensor is changed through the micron-sized wrinkles, so that the concentration of the organic gas can be obtained according to the change of the light transmittance of the gas sensor, the dynamic response to the organic gas is realized, and afterthe detection is completed, the micron-sized wrinkles can disappear, so that the second composite layer is restored to a smooth surface, and the dynamic reversibility is realized.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a gas sensor based on swelling dynamic response and a preparation method thereof. Background technique [0002] At present, intelligent sensing and interactive electronics is an important direction for the development of information technology. The focus of materials and device preparation and development has shifted from static response to dynamic response and intelligence. Gas sensors, as devices in sensing and interactive electronics, also need to However, the existing gas sensors can only sense external stimuli statically, and lack dynamic reversible response functions. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a gas sensor based on swelling dynamic response and a preparation method thereof, which can realize dynamic and reversible dual-signal response to organic gas. [0004] The specific technic...
