Abstract

The invention discloses a preparation method of an intelligent building sensor with pressure-sensitive performance, and relates to a preparation method of a sensor with pressure-sensitive performance.The invention aims to solve the technical problems that an existing building safety evaluation method is large in sampling difficulty, heavy in test instrument and lack of data detection and analysisin result, and when a high-rise building or a super high-rise building is detected, the workload is huge, and core drilling sampling has certain destructiveness. The graphene oxide-based clay compound sensor prepared by the invention has excellent pressure-sensitive performance, and a test shows that the sensor outputs a resistance change curve with the same sinusoidal change when applying a periodically changed sinusoidal load. The sensor is simple in structure and long in service life, and tests show that the sensor can still output a corresponding sine resistance change curve when 1000 times of cyclic sine loads are applied.

Description

technical field [0001] The invention relates to a preparation method of a sensor with pressure-sensitive performance. Background technique [0002] At present, the evaluation of building safety is mainly carried out by means of observation and analysis of cracks or core sampling. These methods not only have many problems such as difficult sampling, heavy testing instruments, and lack of data detection and analysis in the results, but also have many problems in high-rise buildings or super-high-rise buildings. When testing high-rise buildings, the workload is huge, and core sampling is destructive to a certain extent. Therefore, the evaluation of building safety urgently needs further development and optimization. Intelligent building sensors can not only obtain the performance data of the building, but also perform real-time monitoring, which is conducive to understanding the working conditions of the building in real time, and the sensor itself is a building component, and ...
