Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As depicted in figs. 1 and 2, the highly sensitive flexible strain transducer of a kind of wide range, including current sensing element 1 and leads
Electric silica gel 2, the electric silica gel 2 are wrapped in outside current sensing element 1, and the current sensing element is because of the different electricity of flexural deformation
Resistance is different.
In the present embodiment, 2 lower surface of electric silica gel is equipped with adhered layer 5.
In the present embodiment, the adhered layer 5 is hot melt adhesive layer.
In the present embodiment, the current sensing element 1 is sheet metal, and the sheet metal surface is provided with multiple elongated slots 3, and institute
Elongated slot 3 is stated as fine elongated slot, and the sheet metal both ends are provided with the through-holes of multiple perforation upper and lower surfaces, between adjacent elongated slot 3
Spacing is equal, and all elongated slots 3 are equal in length.
In the present embodiment, the sheet metal is strip, and the elongated slot 3 is perpendicular to the long side of sheet metal, and the elongated slot 3
Length be not more than sheet metal width.
The operation principle of the sensor of the utility model is：The utility model include highly sensitive current sensing element and
The big electric silica gel of deformation range, in the present embodiment, the current sensing element is sheet metal, and the sheet metal both ends are provided with
The through-holes of multiple perforation upper and lower surfaces, since sheet metal surface both ends are provided with multiple through-holes, meeting during electric silica gel coated metal piece
It is filled into through-hole, is relatively fixed the position of electric silica gel and sheet metal, it is ensured that sheet metal is under the effect that is stressed
Deformation can be generated without relative displacement occurs with the electric silica gel of outer layer.
In the present embodiment, the current sensing element 1 is sheet metal, and multiple fine elongated slots are provided on sheet metal, is made
Sheet metal generates deformation when being stressed effect, the gap among elongated slot due to sheet metal deformation quantity increase and increasingly
Greatly, so as to cause the increase of entire sheet metal resistor, therefore the sheet metal of this design feature has the characteristics that high sensitivity.When
Deformation quantity increase to a certain extent when, the gap among elongated slot is excessive so that resistance approach infinity, then can not pass through resistance
Value measures deformation quantity, that is, has exceeded sheet metal range, at this time sensor using the big electric silica gel of measurement range come complete
Into measurement.
When flexible strain transducer is by compared with small strain, current sensing element is more more sensitive than electric silica gel, phase similar shape
Current sensing element resistance variations become apparent from than electric silica gel under variable, can measure more accurate strain data, make flexible answer
Becoming sensor has higher sensitivity, when flexible strain transducer is by large strain, because being coated in electric silica gel
Current sensing element has been more than range ability, and the electric silica gel resistance variations that measurement obtains due to deformation are more accurate, lead at this time
The resistance variations for crossing electric silica gel measure corresponding strain data.
The utility model combines the advantages of current sensing element of high sensitivity and measurement range big electric silica gel,
When sensor deformation is smaller, the data measured using the current sensing element of high sensitivity are more accurate；When deformation is larger and surpasses
When having gone out the measurement range of current sensing element, carry out measurement data using the larger electric silica gel of range.The utility model it is soft
Property strain transducer have that measured value range is big, advantage with high accuracy, while preparation method is simple can incite somebody to action this by hot melt adhesive
The flexible strain transducer of utility model is pasted by the way that hot pressing hair is firm on clothing, makes flexible strain transducer wearable,
Have a wide range of application, it is not easily to fall off, it can use for a long time.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
