Abstract

The invention relates to the technical field of sensors, in particular to a micro-nano optical fiber hydrogen sensor and a detection system. The sensor comprises a sensor body and an induction layer. The sensor body comprises an induction part, a first conduction part, a first transition part, a second transition part and a second conduction part, the first transition part is connected to the portion between the first conduction part and one end of the induction part, and the second transition part is connected to the portion between the second conduction part and the other end of the induction part. The first conduction part and the second conduction part are in a column shape, the induction layer comprises a first induction layer and a second induction layer, the first induction layer is arranged on the surface of the first transition part, the induction part and / or the second transition part, and the second induction layer is arranged on the first induction layer. The micro-nano optical fiber hydrogen sensor and the detection system are high in sensitivity and short in response time.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a micro-nano optical fiber hydrogen sensor and a detection system. Background technique [0002] As a new type of green energy, hydrogen energy is widely distributed (hydrogen can be produced with water), renewable and inexhaustible, non-polluting, high energy density and wide application, etc. It is more and more favored by people, and it is widely used in chemical industry, aerospace , military industry and other industries have been widely developed and applied. [0003] Hydrogen is a flammable and explosive gas, and it is very easy to explode when mixed with air. In order to ensure the safety of the industrial production process and use of hydrogen, a hydrogen sensor is needed to detect it. As one of the basic key technologies for the development and utilization of hydrogen energy, hydrogen detection technology is becoming more and more important in its research and develop...
