Problems solved by technology

[0004] When measuring a load whose size cannot be determined, due to the influence of errors, the error rate can be small when measuring a large load; but the error rate is relatively large when measuring a small load
This makes the accuracy of measuring small loads very low, which brings a large error rate to industrial applications and experiments

Abstract

The invention relates to an intelligent sensitivity regulation sensor and a test method thereof. The intelligent sensitivity regulation sensor comprises nanometer porous metal material layers and an insulator layer which are arranged by alternate stacking; the outer surface of the nanometer porous metal material layers are load acting surfaces; a resistance strain foil is fitted on the surfaces of the nanometer porous metal material layers and the insulator layer; all the nanometer porous metal material layers and the insulator layer are soaked in an electrolyte solution; one end of a power supply is connected to a load acting surface, and the other end of the power supply is connected to another load acting surface. The test method applying the intelligent sensitivity regulation sensor comprising following steps: (1). assembling the nanometer porous metal material layers, the insulator layer and the resistor strain foil; (2) blending the electrolyte solution; (3) putting through the power supply; (4) applying loads. By use of the sensor and method, large error rate in small load measurement is avoided.

Description

technical field [0001] The invention relates to a sensor for intelligently adjusting sensitivity and a testing method thereof. The sensor adjusts the sensitivity to voltage changes through the mechanical properties of nano-porous metal materials in an electrolyte, and belongs to the technical field of sensors. Background technique [0002] Nanoporous metal is a new type of functional material developed in the past ten years. It is a porous foam material with nanoscale pores, high surface area and bicontinuous pores. In addition to the advantages of light weight, high specific strength, flame retardant and heat insulation, energy absorption and vibration reduction, sound absorption and noise reduction, and explosion-proof of macroscopic metal foam materials, nanoporous metals also have many unique properties, such as catalysis, surface pull Mann scattering, actuation, filtration and adsorption, etc., have broad application prospects in cutting-edge fields such as catalytic ca...
