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 generally refers to utilize the principle of electric capacity to transmit a kind of device or the device of signal on directions X and 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 Y-direction, and it is laid in respectively both sides or a side of glass pedestal.When two-layer electrode component is not laid in the both sides of glass pedestal, in order to prevent two-layer electrode group mutual conduction, need to punch on glass substrate, its one deck electrode group is connected successively from the opposite side in hole, thereby has avoided mutually opening circuit of two-layer electrode group; If two lateral electrode groups are laid in the same side of glass substrate, also another substrate need be set between two-layer electrode group, be used for isolating two-layer electrode group, but this layout need to 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 affect in punching on substrate the electrode group on another layer from one deck electrode group wherein being connected with each other.But this method can produce impedance unavoidably, thereby affects driving force; Moreover no matter the electrode group is to be laid in which way on substrate, adopts the technique of two-layer electrode group certainly than the complex process of only having one deck electrode group.
Therefore need to 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 technique 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 a side of substrate, and described one deck electrode group is provided with the electrode of both direction, wherein, electrode on direction is linked in sequence successively, described substrate is provided with groove, is filled with the conductor that can produce deformation in described groove, and the electrode on another direction is by the conductor mutual conduction in groove.
Capacitive transducer of the present invention, owing to only having utilized one deck electrode group just to overcome the problem of both direction top electrode group mutual conduction, thus not only simpler on technique, and impedance is low, thus improved the driving force of whole device.

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 comprised of some diamond blocks 12.
Please refer to again shown in Figure 2, described rhombus electrode block 12 respectively vertically and row to arrangement, during described diamond block 12 longitudinal arrangement, in every row, each rhombus electrode block 12 is linked in sequence successively; When described diamond block 12 is transversely arranged, for fear of the mutual conduction between electrode, so can not be linked in sequence successively on above-mentioned side this moment, can be chosen between the electrode of laterally arranging on substrate 10 and offer a groove 13, please refer to shown in Figure 4ly, described groove 13 extends on adjacent another one electrode from an electrode in a lateral direction.Conductor in transparent the produced deformation of the interior filling of above-mentioned groove 13, 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 complete conductor after interior to groove 13, so, just the electrode group that is laid on a direction of substrate 10 1 sides can be made mutual conduction between electrode by the conductors in groove 13, can not have influence on again the electrode group on another direction simultaneously.Because the one deck in two-layer electrode group is realized conducting by filling conductor in groove, thus the impedance of whole device will greatly reduce, thereby improved driving force.
The method that electrode group on 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 utilizing one deck electrode group, thus must be than with two-layer electrode group on technique simple.
Capacitive transducer of the present invention, owing to utilizing one deck electrode group to replace traditional two-layer electrode group to be laid in mode on substrate, overcome the problem of both direction top electrode group mutual conduction, so not only simpler on technique, and impedance is low, thereby has improved the driving force of whole device.
