Specific embodiment
Below in conjunction with the accompanying drawings the structural principle and operation principle of the present invention is described in detail:
Fig. 1 is the structural representation of the touch sensing device 100 of first embodiment of the invention, in order to illustrate touch base plate 10
And the configuration of multiple first strain gauge 20.Fig. 2 be schematically shown as touch sensing device 100 on regarding structural representation.Please merge reference
Fig. 1 and Fig. 2, touch sensing device 100 includes: touch base plate 10 and multiple first strain gauge 20, and every one first strain gauge 20 is flat
Row configures in touch base plate 10 in first direction x, and every one first strain gauge 20 includes multiple sensitive grids 21 of concatenation.Specifically
It, the head of every one first strain gauge 20, tail two ends are respectively provided with sensitive grid 21a, also concatenate multiple quick between two sensitive grid 21a
Sense grid 21b, is respectively adjacent to border 11 and border 12, border 11 and the border in touch base plate 10 positioned at the sensitive grid 21a at two ends
12 opposite sides being located at touch base plate 10.When being bent, the first strain gauge 20 on touch base plate 10 will be in response to being subject to
Produce sensing to active force.
Fig. 3 shows and is bent by identical external force when each sensitive grid 21 of the first strain gauge 20 of touch sensing device 100
When, simulate the schematic diagram of the strain of each sensitive grid 21.Please merge with reference to Fig. 2 and Fig. 3, the sensitive grid in every one first strain gauge 20
21 straining and sensing direction is all substantially parallel to first direction x.Strain gauge (strain gauge) based on resistance calculates public
Formula: △ r=r × ε × gf, wherein, △ r is the resistance change amount of material, and r is the initial resistivity value of material, and gf is material
The coefficient of strain (gauge factor), ε is the strain at measuring point.When every one first strain gauge 20 is configured on touch base plate 10
When, because the active force that border 11 and border 12 are produced to sensitive grid 21a to position can make positioned at border 11 and border 12
On sensitive grid 21a strain stress x that presses power in response external be more than remaining sensitive grid 21b response external and press power
Strain stress x, so that strain stress x with the sensitive grid 21a at two ends is different from strain stress x of remaining sensitive grid 21b, and makes
The △ r variable quantity that sensed with remaining sensitive grid 21b of sensitive grid 21a becoming two ends in touch base plate 10 differs, specifically and
Speech, the △ r variable quantity that in touch base plate 10, the sensitive grid 21a at two ends is sensed will be sensed more than remaining sensitive grid 21b
△ r variable quantity.
Therefore, in the first embodiment of the invention, utilize the head in every one first strain gauge 20, two sensitive grids of tail
The resistance of 21a is smaller than the resistance of remaining each sensitive grid 21b in the first strain gauge 20, or, answer using by every one first
Become the head in meter 20, the coefficient of strain of two sensitive grid 21a of tail is smaller than remaining each sensitive grid 21b in the first strain gauge 20
The coefficient of strain it becomes possible to strain stress x of sensitive grid 21a at the two ends of the first strain gauge 20 that differs of balance is quick with remaining
The impact caused by strain stress x of sense grid 21b, and make the △ r variable quantity that in touch base plate 10, each sensitive grid 21 is sensed close
Identical.
Wherein, sensitive grid 21a and sensitive grid 21b can be metal sensitive grid or nonmetallic sensitive grid.Additionally, at remaining
In embodiment, as long as each sensitive grid 21 in touch base plate 10 can be made to meet computing formula: felt after △ r=r × ε × gf
, under the conditions of identical, in touch base plate 10, the resistance of each sensitive grid 21a and the coefficient of strain can be identical for the △ r variable quantity surveyed
Or different, and in touch base plate 10, the resistance of each sensitive grid 21b and the coefficient of strain may be the same or different.That is, this
Invent described embodiment to be used for illustrating, be not intended to limit the component attributes such as material or the resistance matter of each sensitive grid 21.
For example, each sensitive grid includes at least one coiling, due to around the number of turns the more then resistance bigger, thus can be via
Make remaining in the number of turns smaller than the first strain gauge 20 of head in every one first strain gauge 20, two sensitive grid 21a of tail every
One sensitive grid 21b around the number of turns so that making the resistance of sensitive grid 21a be less than the resistance of remaining each sensitive grid 21b.Or,
Because the bigger then resistance of the sectional area of coiling is less, thus can be by the head making in every one first strain gauge 20, two sensitivities of tail
The sectional area of the coiling of grid 21a is all more than the sectional area of the coiling of remaining each sensitive grid 21b in the first strain gauge 20, so that
It is less than the resistance of remaining each sensitive grid 21b in the resistance making sensitive grid 21a.Or, make in every one first strain gauge 20
Head, the resistance value of the material of two sensitive grid 21a of tail are smaller than the material of remaining each sensitive grid 21b in the first strain gauge 20
Resistance value so that make sensitive grid 21a resistance be less than remaining each sensitive grid 21b resistance.
Furthermore, can be smaller than via the coefficient of strain of the head making in every one first strain gauge 20, two sensitive grid 21a of tail

Material concretely adulterate the tin indium oxide (ito) of different metal concentration.In detail, when silver-colored concentration is close to zero, ito
The coefficient of strain be about " -1.5 " to " -3.8 ".But, if silver-colored concentration is lifted the coefficient of strain of 10, ito
About approach as " 4 ".If also, the coefficient of strain that silver-colored concentration is lifted percent 20, ito can reach and is close to " 7 ".
In certain embodiments, can be via using different materials, to cause the strain system of head, two sensitive grid 21a of tail
Number is smaller than the coefficient of strain of remaining each sensitive grid 21b.For example: in the case of external condition identical, copper (copper)
The coefficient of strain is 2.6, and the coefficient of strain of platinum/platinum (platinum) is 6.1, and semiconductor material is then according to its strain of variable concentrations
Coefficient is even up to 100.Based on aforementioned, in can making touch base plate 10, each sensitive grid 21 meets computing formula: △ r=r
, under the conditions of identical, those skilled in the art should be by consulting various elements for the △ r variable quantity being sensed after × ε × gf
Attribute forming the sensitive grid 21 in touch base plate 10.
In certain embodiments, the material concretely titanium of the head in the first strain gauge 20, two sensitive grid 21a of tail
(ti), or sensitive grid 21a material concretely aluminum (al), and remaining each sensitive grid 21b in the first strain gauge 20
Material concretely copper (copper).However, the present invention is not limited, those skilled in the art should understand that aforementioned adjustment is sensitive
The purpose of the resistance of grid and/or the coefficient of strain is strain and remaining sensitive grid of the sensitive grid at the two ends for balancing strain gauge
Strain differs caused impact.
