Survey and sense, and the thickness of product is smaller.
Alternatively, the set location of pressure sensitive layer 30 and capacitive sensing layer 20 can be configured as needed.For example,
Pressure sensitive layer 30 may be located at top, the under or within of capacitive sensing layer 20.That is pressure sensitive layer 30 and capacitive sensing layer
20 can be simple structure stacked on top of one another, or insert structure, specifically can be according to specific feelings using which kind of structure
Condition is configured.
For example, in one embodiment of the present utility model, capacitive sensing layer 20 can include two-layer electrode layer, feeling of stress
Layer 30 is answered to may be located between two-layer electrode layer, capacitive sensing layer 20 and pressure sensitive layer 30 may be located at cover sheet 10 and aobvious
Show between module 110.
Set location of each detecting electrode to two electrodes 331 in 33 on resistance-type pressure sensitive part 31 is not limited
System, as long as two electrodes 331 are spaced apart.Alternatively, as depicted in figs. 1 and 2, in some embodiments of the present utility model
In, any one detecting electrode can be located at the same side of resistance-type pressure sensitive part 31 to two electrodes 331 in 33, i.e.,
Two electrodes 331 can be each provided on the upper surface of resistance-type pressure sensitive part 31 or lower surface.Thus, manufacture is not only facilitated,
And the measurement of resistance variations can be realized.
Alternatively, as shown in Fig. 3 to Figure 17, in other embodiments of the present utility model, any one detecting electrode
Two electrodes 331 in 33 can be located at the opposite both sides of resistance-type pressure sensitive part 31 respectively.That is, detection electricity
Extremely an electrode 331 (i.e. Top electrode 331a) in 33 is located on the upper surface of resistance-type piezoresistive material part 31, another
Electrode 331 (i.e. bottom electrode 331b) is located on the lower surface of resistance-type pressure sensitive part 31.When pressure sensitive layer 30 is pressurized, electricity
Resistance between the upper surface of resistive pressure sensitive 31 and lower surface can occur more obviously change.Therefore, it can according to each
Detecting electrode judges the variation relation of the resistance of the resistance between 33 size information of power when position and the pressing of pressing.By
This, not only facilitates and sets, and detection is easier and accurate, and Detection results are more preferable.
Referring to figs. 1 to shown in Figure 17, according to some embodiments of the present utility model, each electrode 331 can be formed respectively
It is block or strip, the multiple electrodes 331 positioned at the same side of resistance-type pressure sensitive part 31 can be arranged in array, for example,
In matrix arrangements.Thus, electrode 331 is more evenly distributed suitably on resistance-type pressure sensitive part 31, it is possible to achieve multiple positions
The detection of the touch pressure at place, Detection results more preferably, and are conveniently manufactured.
For example, as depicted in figs. 1 and 2, each detecting electrode can be formed as block to two electrodes 331 in 33,
And it is distributed in the same side of detection resistance formula pressure sensitive part 31.Wherein, two electrodes 331 closer to the distance can be formed
One detecting electrode is to 33, for example, A and A ' may be constructed a detecting electrode may be constructed a detecting electrode to 33, B and B '
A detecting electrode can also be constituted to 33, C and C ' to 33, each electrode pair 33 can realize the detection of touch pressure.Can
Selection of land, electrode 331 can be produced on resistance-type pressure sensitive part 31 by modes such as evaporation, spraying, silk-screens.
Again for example, as shown in Figure 6 to 8, any one detecting electrode is respectively provided at resistance to two electrodes 331 in 33
The opposite both sides of formula pressure sensitive part 31, Top electrode 331a is located on the upper surface of resistance-type pressure sensitive part 31, bottom electrode
331b is located on the lower surface of resistance-type pressure sensitive part 31.Pressure sensitive device 100 can also include basalis 34, basalis
34 can be located on two surfaces of the side of the dorsad resistance-type pressure sensitive part 31 of electrode 331.That is, basalis 34
Upper basalis 341 and lower basalis 342 can be included, upper basalis 341 is located on the upper surface of Top electrode 331a, lower basalis
342 are located on the lower surface of bottom electrode 331b.Thus, the resistance-type pressure sensitive part 31 for being provided with detecting electrode to 33 can be pressed from both sides
It is located between basalis 341 and lower basalis 342, the structural behaviour of pressure sensitive device 100 more preferably, is further ensured that detection
Effect.
Alternatively, electrode 331 can be prepared in basalis by modes such as evaporation, coating, silk-screen, vapour depositions (CVD)
On 34, be formed as block resistance-type pressure sensitive part 31 can by the modes such as coating, silk-screen belt electrode pattern substrate
It is prepared on layer 34.
In more preferably embodiment more of the present utility model, each detecting electrode can to two electrodes 331 in 33
To be located at the both sides of resistance-type pressure sensitive part 31 and have overlap in the horizontal direction.That is, each detecting electrode pair
An electrode 331 in 33 is located at resistance-type pressure sensitive part upside, and another electrode 331 is located at resistance-type pressure sensitive part 31
Downside, in the vertical direction is projected downwards, and the projection of two electrodes 331 has overlapping region or intersection region.In other words, two
There is facing portion point in the in the vertical direction of electrode 331.Thus, the two electrodes 331 can be with detection resistance formula pressure sensitive part 31
The resistance variations of in the vertical direction, Detection results are more preferable.
Further, as shown in Figures 3 to 8, each detecting electrode can be formed as respectively to two electrodes 331 in 33
The vertical strip of bearing of trend.Also just say, each detecting electrode is distributed in resistance-type pressure sensitive to two electrodes 331 in 33
The both sides of part 31, two electrodes 331 are all formed as strip, and bearing of trend is in 90 degree.Thus, manufacture is not only convenient for, and
Two electrodes 331 can be overlapped in the horizontal direction, it is ensured that preferable Detection results.
It should be noted that the structure of pressure sensitive layer 30 described above is only described as an example, feeling of stress
Answer the structure not limited to this of layer 30, group of the pressure sensitive layer 30 according to the shape of electrode 331, distributing position and arranging situation etc.
Closing change can form various different structures, however it is not limited to the structure shown in accompanying drawing, and this comes to those skilled in the art
Say and will be understood by, and these structures also will be within protection domain of the present utility model.
In addition, for the structure with basalis 34, on basalis 34 in addition to detecting electrode is set to 33 also
Some structures of capacitive sensing layer 20 can be set.For example, as shown in Figure 15-Figure 17, capacitive sensing layer 20 can include reaching the standard grade
Electrode 221 and lower line electrode 222, upper line electrode 221 can be located on the lower surface of basalis 341, and lower line electrode 222 can be with
It is located on the upper surface of lower basalis 342.Capacitive sensing layer 20 and pressure sensitive layer 30 can be formed as interspersed structure, two senses
Answer layer common base layer 34.Thus, it is possible to improve space availability ratio, thickness and cost are reduced.
In addition, in the structure shown here, because the detecting electrode of pressure sensitive layer 30 needs to be connected directly to mix conductive particle to 33
Son resistance-type pressure sensitive part 31 both sides, therefore to capacitive sensing layer 20 upper line electrode 221 carried out with lower line electrode 222
The optical clear glue-line (OCA) of laminating can take borehole to process in the position of resistance-type pressure sensitive part 31, that is, open up through hole
101, as shown in figure 18, to ensure Detection results.
