Abstract
The utility model provides a PVDF piezoelectricity film glue sealing strain gauge screened by metal screening layer, which comprises a PVDF piezoelectricity film wrapped with glue substrates at the two sides, and the two are integrated as a whole. A metal screen net is positioned at the outside of the substrate, and an electrode and a sector conductor are positioned at the ends of the PVDF piezoelectricity film. The utility model has the advantages of simple structure, low cost, convenient production of the PVDF piezoelectricity film sensor of the same specification; high precision of the strain gauge, strong resistance of electromagnetic disturbance, and resistance of moisture and corrosion.
Description
(1) technical field
The utility model is a kind of suitable novel intelligent strainometer of monitoring with the civil engineering structure long-term health.
(2) background technology
Since 1880 by Frenchman Jacques Curie and Pierre Curie in quartzy (α 2SiO2) after the discovery piezoelectricity, people have found a large amount of natural and artificial piezoelectric monocrystals in succession in the inorganics scope, pottery and film, finds that on organism piezoelectricity appears at the impact induced polarization that people such as .1965 Harris and Allison in the Briain paper of (nineteen twenty-four) has tested plastics the earliest and break through the inorganics field. increasingly extensive to the research of boiomacromolecule piezoelectricity subsequently. much people are once to wood, silk, bone, muscle etc., and RNA (ribonucleic acid) (RNA), DNA (deoxyribonucleic acid) (DNA) is studied, find that it all has certain people such as piezoelectricity .Peterlin and has observed in 1967 and roll the ε value of prolonging polyvinyladine floride (PVDF), also confirmed its piezoelectricity. (H.Kawai) closed in beginning the ground-breaking research of PVDF piezoelectric effect in 1969 in the river of Japan. and the same period, Fukada pointed out after also having done the piezoelectricity research of a large amount of biopolymers, the piezoelectricity of PVDF and biopolymer is different, the piezoelectric strain coefficient maximum that it demonstrates on the incipient extension direction (d31＞＞d32) Beishan Mountain of .1972 Japan, the flexible composite of PVDF+BaTiO3 has been manufactured experimently in middle village's cooperation, opened up the new way of piezoelectric high polymer 2 piezo-electric ceramic composite materials again, make piezoelectric high polymer step a step again to the practical research direction. nowadays, PVDF and other piezoelectric high polymer are made various piezo components as a kind of extremely promising novel piezoelectric material, beginning is expanded to science and technology and industry direction. as a kind of novel structure intelligent sensing element, the pvdf piezoelectric membrane has plurality of advantages, as: highly sensitive, the face monitoring, light weight, volume is little, response is fast, the pressure measurement scope is big, signal attenuation is little, good economy performance etc., make it become after a kind of relay resistance foil gauge and the fiber grating a kind of novel sensor that in structure monitoring, should be widely promoted.Because pvdf piezoelectric membrane thickness is very little, about about 100 microns, its principal ingredient is a polyvinylidene fluoride greatly, and tensile strength is low, and shear resistance is poor, the quality fragility.Be difficult under the rugged surroundings of Construction of Civil Engineering, survive, must take effectively encapsulation measure to protect.So need a kind of good method for packing, can be suitable for the laying of sensor, guarantee the survival of pvdf piezoelectric membrane, can guarantee that again the good interface of strain is transmitted performance.
(3) summary of the invention
The purpose of this utility model is to provide a kind of industrialization production that is suitable for, and simple in structure, cost is lower; Strain monitoring precision height is suitable for the PVDF piezoelectric film glue base package strain meter of the metal screen layer shielding of complicated body structure surface form.
The purpose of this utility model is achieved in that it comprises the PVDF piezoelectric membrane, be surrounded by the matrix sheet in the both sides of PVDF piezoelectric membrane, PVDF piezoelectric membrane and matrix sheet are bonded to one, and are outside equipped with the metallic shield net at substrate, and there is electrode the end of PVDF piezoelectric membrane and draws lead.
The Pvdf piezoelectric membrane is highly sensitive, is subject to external interference.When being used in it on more civil engineering structure of interference, obtain beyond thought error result sometimes.To with it large-scale application in the civil engineering structure monitoring, just must effectively shield, can be real in operation to guarantee the pvdf piezoelectric membrane, stable collection and transmission signals, thus improve its service efficiency.
The utility model is sought a kind of metal material, and this material is satisfying under the frivolous gentle prerequisite, has good strain and transmits performance.Through verification experimental verification, the utility model adopts sensing to shield with metal pair pvdf piezoelectric membrane, and the pvdf piezoelectric membrane is sticked in the middle of the two-layer matrix, does complete one deck gauze screen in packaged pvdf piezoelectric membrane outside.
This utility model has the following advantages: 1, be suitable for industrialization production, and simple in structure, cost is lower; 2, strain monitoring precision height, metal screen layer almost has no impact to the sensing capabilities of packaged pvdf piezoelectric film sensor; 3, because screen layer and encapsulation matrix are all very gentle thin, be suitable for complicated body structure surface form.
Structure of the present utility model can be made the shielding pvdf piezoelectric membrane encapsulation strainometer of multidimensional easily.
(4) description of drawings
Accompanying drawing is the structural representation of embodiment of the present utility model.
(5) embodiment
The composition of the PVDF piezoelectric film glue base package strain meter of metal screen layer shielding comprises PVDF piezoelectric membrane 1, be surrounded by matrix sheet 2 in the both sides of PVDF piezoelectric membrane, PVDF piezoelectric membrane and matrix sheet are bonded to one, be outside equipped with metallic shield net 3 at substrate, there is electrode 4 end of PVDF piezoelectric membrane and draws lead 5.The matrix that its structure is formed encapsulation is to guarantee it and structure cooperative transformation, and beyond the distortion situation of reflect structure, the outside has one deck complete metallic shield net and strainometer to be pasted together.
