Abstract
The invention relates to a capacitance sensor, which comprises a base plate and a layer of electrode groups, wherein the electrode groups are arranged on one side of the base plate; electrodes in two directions are arranged on the layer of electrode groups; grooves are formed between the electrodes in one direction; and deformable conductors are filled in the grooves. In the invention, mutual conduction of the electrode groups in two directions can be realized by only using one layer of electrode groups, and the capacitance sensor is simpler in process and low in impedance, so the driving capacity of the capacitance sensor is improved.
Description
Technical field
The present invention relates to a kind of sensor, refer in particular to a kind of capacitive transducer.
Background technology
So-called capacitive transducer is meant that generally the principle of utilizing electric capacity transmits a kind of device or the device of signal on directions X and the Y direction, can be the ITO(indium tin oxide) layer, pcb board, keyboard or touch-screen etc., usually by people's finger or pointer actuating.Existing capacitive transducer has two-layer electrode group usually, please refer to shown in Figure 1ly, and one deck electrode group is as directions X, and another layer electrode group is as the Y direction, and it is laid in the both sides or a side of glass pedestal respectively.When two-layer electrode group is laid in the both sides of glass pedestal respectively, in order to prevent two-layer electrode group mutual conduction, need on glass substrate, punch, its one deck electrode group is connected successively from the opposite side in hole, thereby has avoided opening circuit mutually of two-layer electrode group; If two lateral electrode groups are laid in the same side of glass substrate, then between two-layer electrode group, also another substrate need be set, be used to isolate two-layer electrode group, but this layout need punch on substrate equally, be about to one deck electrode group wherein and be connected successively from the opposite side in hole.
The mode of above-mentioned two-layer electrode group wiring, no matter which kind of wiring, all need two-layer electrode group, and for fear of two-layer electrode group mutual conduction, must be unlikely to influence electrode group on another layer from one deck electrode group wherein being connected with each other in punching on the substrate.But this method can produce impedance unavoidably, thereby influences driving force; Moreover no matter the electrode group is to be laid in which way on the substrate, and the technology that adopts two-layer electrode group is certainly than the complex process of having only one deck electrode group.
Therefore need solve above problem for users provide a kind of easier capacitive transducer.
Summary of the invention
The actual technical matters to be solved of the present invention is how the capacitive transducer that a kind of technology is simple and impedance is low is provided.
In order to realize above-mentioned purpose of the present invention, the invention provides a kind of capacitive transducer, it comprises substrate and one deck electrode group, described electrode group is laid on the side of substrate, described one deck electrode group is provided with the electrode of both direction, wherein, be provided with groove between the electrode on direction, be filled with the conductor that can produce deformation in the described groove.
Capacitive transducer of the present invention, owing to only utilized one deck electrode group just to overcome the problem of both direction top electrode group mutual conduction, thus not only simpler on the technology, and impedance is low, thus improved the driving force of whole device.
Description of drawings
Fig. 1 is the layouts figure of existing capacitance sensor electrodes group.
Fig. 2 is the structural drawing according to capacitive transducer of the present invention.
Fig. 3 is the structural drawing according to capacitance sensor electrodes group of the present invention.
Fig. 4 is the structural representation according to electrode group groove of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Please in conjunction with referring to figs. 2 and 3 shown in the structural drawing of capacitive transducer, described sensor 1 comprises substrate 10 and one deck electrode group 11, wherein electrode group 11 is laid in a side of substrate 10, described electrode group 11 is made up of some diamond blocks 12.
Please refer to again shown in Figure 2, described rhombus electrode block 12 respectively vertically and row to arrangement, when described diamond block 12 was vertically arranged, each rhombus electrode block 12 was linked in sequence successively in every row; When described diamond block 12 is transversely arranged, for fear of the mutual conduction between the electrode, so can not be linked in sequence successively on above-mentioned side this moment, can be chosen in and offer a groove 13 between the electrode transversely arranged on the substrate 10, please refer to shown in Figure 4ly, described groove 13 extends on the adjacent another one electrode from an electrode in a lateral direction.In above-mentioned groove 13, fill the conductor of transparent produced deformation, as common salt solution, electrically conducting transparent glue or transparent monox liquid etc., with the method for bombardment the above-mentioned conductor filled filling that can finish conductor to groove 13 after interior, so, just the electrode group that is laid on the direction of substrate 10 1 sides can be made mutual conduction between the electrode by the conductors in the groove 13, can not have influence on the electrode group on another direction simultaneously again.Because the one deck in the two-layer electrode group is realized conducting by filling conductor in the groove, thus the impedance of whole device will reduce greatly, thereby improved driving force.
The method that electrode group on the both direction is laid in substrate one side of the present invention, not only can be good at avoiding the electrode problem of conducting each other, and can reduce impedance, improve the driving force of whole device, moreover, owing to only utilize one deck electrode group, thus on the technology must than with two-layer electrode group simply.
Capacitive transducer of the present invention, owing to utilize one deck electrode group to replace traditional two-layer electrode group to be laid in mode on the substrate, overcome the problem of both direction top electrode group mutual conduction, so it is not only simpler on the technology, and impedance is low, thereby has improved the driving force of whole device.
