Specific embodiment

Below to the utility model relates to structure or technical term used in these be described further, if do not had It specializes, general according to this field is typically belonged to be understood and explained.

Humidity DetectionHumidity Detection indicates the amount of liquid or steam, and liquid includes being not limited to: the excrement of urine, carrying liqs Just, the water that blood, tissue fluid, secretion, saliva, pure water, rainwater, Water vapor condensation are formed, the hot vapour condensation of body surface The secretion or excreta of formation；Steam includes being not limited to: evaporating the vapor of formation, the steam in humid air, human body The hot vapour of body surface, the steam in solid or semisolid excreta.In addition, Humidity Detection indicates the range of scatter of liquid.

Electrochemical mediators electrochemical mediators are that one kind is non-conductive when dry, and conductive substance, this when moistening Substance is arbitrary chemical substance.For example, inorganic salts when dry, be in itself it is nonconducting, when inorganic salts be dissolved when It waits, such as water is as solvent, with the presence of free ion in solvent, thus conductive.This substance also can be that chemistry occurs instead The substance answered, for example, when these substances it is dry when it is non-conductive when dissolved, have occurred chemical change to Ion is produced, conduction is caused.These substances may be, but not limited to, such as inorganic salts (NaCl, MgCl etc.), or with It is a kind of containing at least a polarity or the hydrophilic polymer of charged functional groups etc., electrochemical mediators 4 have active hygroscopicity.Poly- Close and often contain hydrophilic functional group in owner's chain or side chain, including but not limited to CONH2- ,-OH ,-CONH ,-COOH ,- SO₃H ,-NH₂.For example, acrylic compounds include but is not limited to acrylic acid, acrylamide and polyethylene etc. and modified or by above-mentioned Polymer precursor is copolymerized the copolymer of formation each other.Amine functional polymer includes but is not limited to allyl amine, aziridine, alkene Pure and mild other polymer in its main chain or side chain containing amido.

For example, some reagents of these test urines perhaps blood glucose in blood are when encountering urine or blood, With certain a kind of analyte in urine or blood, so as to cause chemical reaction, so as to cause conductive substance.

This humidity sensor of signal system is generally required to be used cooperatively with signal system, when liquid moistens humidity sensor Indicate user.For example, on the one hand, signal system is designed to issue signal when humidity sensor detects liquid.But this Humidity sensor can be matched with existing signal system, and the structure of humidity sensor is not needed the structure of signal system, detection Scheme is included.

The humidity sensor of humidity sensor the utility model is that one kind can be manufactured independently, be matched with any article to be measured Close, no plain conductor, can active moisture absorption, and after wet identification amount of liquid and or humidity range, can be with direct body contact's Sensor.

As shown in Fig. 1,3,5,6,8,9,12, humidity sensor, including substrate has coated conducting wire and Humidity Detection on substrate Portion S, humidity detection unit S at least one, each humidity detection unit S have at least two electrodes, and each electrode is led with respective coating Line is connected, conductive electrochemical mediators when insulating when having dry between electrode, is wet.Coated conducting wire is with conducting resinl (such as conductive silver Glue, conductive carbon paste) or biochemical ink etc. conductor wire on base material is set by way of printing or coating.

In use, substrate to be fixed on to the surface of absorbent commodity, humidity sensor is directly and human contact；Liquid substance When appearance, liquid first directly contacts humidity sensor, absorbs in absorbability article.The humidity detection unit S's for having liquid wet Electrochemical mediators become conductor from insulator, and two electrodes become short circuit from open circuit, export electric signal outward.

It is that substrate can be insulation but have spongy material or substrate is insulation in some modes, but It is the property without water suction.When substrate is insulation but does not have water imbibition, if the electrochemistry of humidity detection unit Medium it is dry when, it is non-conductive, but when generally moistened by liquid, there is liquid to exist, to allow dry electrification It learns medium or partial electro chemical medium forms electrochemical solution, so as to cause conduction.Here liquid can be any have Solution of hydrone, such as urine, saliva etc. directly contact electrochemical mediators.Substrate can be still having for insulation and absorb water Property material, this when, electrode is disposed on substrate, and has gap between two electrodes without contacting, and in matrix Upper point, the electrochemical mediators coated with liquid, are then dried.When dry, electrochemical mediators are non-conductive, thus two electrodes it Between not no electric current formation.When substrate absorption has liquid, while electrochemical mediators are also moistened, has allowed dry mediated electrochemical Qualitative change is wet or partial electro chemical medium becomes wet, thus forms ion in wet part, so as to cause The generation of electric current between electrode.

Humidity detection unit S

In some embodiments, as shown in Fig. 1,3,5,6,8,9,12,13 and 14, humidity detection unit includes humidity inductive Cell S or T have one or more.Each humidity detection unit S issues Continuity signal when being connected, and multiple humidity detection unit S are led Accumulative Continuity signal is issued when logical.For example, Continuity signal is buzzer, when only one humidity detection unit S is connected, when unit One sound buzzer of interior sending.When there are two humidity detection unit S conducting, two sound buzzers are issued in the unit time；It is N number of when having When humidity detection unit S is connected, N sound buzzer is issued in the unit time.Alternatively, issuing one when a humidity detection unit S conducting The buzz of unit strength when N number of humidity detection unit S is connected, issues the buzz of N* unit strength.Continuity signal can also be Optical signal is transferred to the alerting signal lamp of terminal.The conducting quantity characterization amount of liquid and wetness control range of humidity detection unit S. Alarm signal is transferred to terminal by electric connection structure by electric connection structure identification and sending or alarm signal, by terminal recognition And sending.

Every coated conducting wire connects the electrode of at least one humidity detection unit S.Multiple humidity detection unit S are connected to same root When on coated conducting wire, the electrochemical mediators for the humidity detection unit S not moistened by liquid are insulator, are only had on current coated conducting wire Electric current will not be formed back by the conducting wire that another electrode for the humidity detection unit S that liquid moistens connects with current coated conducting wire Road, therefore multiple humidity detection unit S are set on a coated conducting wire will not cause signal interference, moreover it is possible to save the face of substrate Product.

In some embodiments, each electrode includes the pole plate being connected with conducting wire, electrochemical mediators be set to two pole plates it Between, pole plate is conductive gel coating (rubber layer or elargol layer of such as silk-screen printing).As shown in Fig. 4, Fig. 6 and Fig. 8, Humidity Detection For one of pole plate in portion S within another pole plate, external polar plate has notch, the interconnecting piece of internal polar plate and its coated conducting wire In the notch.Internal polar plate and external polar plate are rounded, and the interconnecting piece of internal polar plate and the interconnecting piece of external polar plate are straightness. With comprising with by comprising form, increase the relative area between two pole plates, to improve the sensitivity of humidity detection unit S.

Alternatively, two pole plates of humidity detection unit S are opposite as shown in Fig. 4,6,9,12,13 and 14.Comb is distributed with along pole plate Tooth is tooth socket between adjacent comb teeth；The comb teeth of two electrodes is opposite.In humidity detection unit S, the comb teeth of one of electrode is inserted Enter in the tooth socket of another electrode, the position between adjacent fingers is tooth socket, has gap between two electrodes, electrochemical mediators are filled out Gap between charging pole.Comb teeth increases the sensing area of electrode, as long as there is the electrochemistry between a pair of of comb teeth in two electrodes Medium, which is wet, can export electric signal, improve the sensitivity to humidity inductive.A part of coated conducting wire as pole plate, or Person, pole plate partially overlap with coated conducting wire, alternatively, pole plate is located at the end of coated conducting wire or the end of pole plate and coated conducting wire Head is connected.

In some embodiments, two electrodes are located on the same floor.Electrochemical mediators partly or completely all standing electrode.Manufacture When, electrochemical mediators solution is added dropwise in humidity detection unit S, then is dried, makes electrochemical mediators in state of insulation.

Alternatively, as shown in Figure 2 and Figure 7, each humidity detection unit S includes a pair of conductive section, has suction between two conductive segments Wet hole fills electrochemical mediators in moisture absorption hole.Liquid enters in moisture absorption hole, and electrochemical mediators become conductor from insulator, and two Conductive segment conducting output electric signal.

Each conductive segment includes rubber layer and elargol layer, and conductive segment is coated in substrate surface, and elargol layer is in rubber layer and substrate Between.Conductive segment one end adjacent with moisture absorption hole is first end, the other end is second end；The second end of elargol layer is wrapped in carbon paste In layer, the second end of elargol layer and the second end of rubber layer are both exposed to moisture absorption hole.In gap between elargol layer and rubber layer There are electrochemical mediators, as shown in Figure 2.Alternatively, elargol layer is wrapped within rubber layer, as shown in Figure 7.

Substrate is the carrier of coated conducting wire, and substrate has water imbibition and hygroscopicity.Liquid or steam first penetrate into base In material, electrochemical reaction occurs after being wet for electrochemical mediators, and corresponding coated conducting wire and the humidity detection unit being wet export Electric signal.Substrate is insulator when dry, after substrate absorbs liquid or steam, when humidity deficit so that electrochemical mediators occur When electrochemical reaction, even if coated conducting wire exports electric signal, which is also insufficient as alarm signal output.If substrate is inhaled The liquid or moisture of receipts only allow between coated conducting wire and moisten, and electrochemical mediators are still the wet of drying regime or electrochemical mediators When degree is not enough to occur electrochemical reaction, even if there is electric signal output between coated conducting wire, humidity detection unit can not also be occurred Electrochemical reaction and the electric signal exported interferes.

Herein, substrate has at least two parts, and a portion processing has electrochemical mediators, and other part is not With electrochemical mediators.The mode of processing can be electrochemical mediators solution and be added dropwise in matrix.It is general any with water imbibition base The substrate that matter all can serve as the utility model comes using such as with water imbibition filter paper, glass fibre, cotton, these moisture absorptions Property or water imbibition are all the absorption or reservation of the water under capillarity.Thus foring on substrate has processing electrification Learn the place and the place of non-process electrochemical mediators of medium.When substrate has water imbibition, it is possible to wet place Do not handled electrochemical mediators, but passed through with conductive coating, this when, processing have electrochemical mediators place not by Wet, although this when is wet in the place that conductive coating passes through, but not will form current lead-through.On the contrary, only After the place of electrochemical mediators processing is wet, the electric current being connected between the electrode of conductive coating can just be caused to generate, thus Cause conduction.

It may be considered that liquid has only moistened the region between any two coated conducting wires but liquid is not diffused into Humidity detection unit (in the humidity detection unit processing have electrochemical mediators), the electric signal occurred between coated conducting wire, the electric signal It is humidity alarm signal that structure recognition, which can not be electrically connected,.For example, electric signal is very weak or even without can not then be electrically connected Structure recognition comes out.

Alternatively, the electric signal as humidity alarm signal has strength range, electric connection structure can only be by the strength range Interior electric signal is identified as humidity alarm signal, if the electric signal between coated conducting wire is lower than under the intensity of humidity alarm signal Limit or upper intensity limit higher than humidity alarm signal, electric connection structure do not identify the electric signal except strength range. For example, theoretically, this two because on substrate there is processing to have the place of electrochemical mediators and the place without electrochemical mediators When encountering identical wet degree, the electric conductivity showed is generally different in a different region.Generally, processing has The conductive capability in the place of electrochemical mediators is greater than the place for not handling electrochemical mediators, because conductive coating may be by not Place with electrochemical mediators, it is also possible to by having the place of electrochemical mediators (forming humidity detection unit), this when, If being applied with voltage between conducting wire, it is greater than in the electric current that processing has the place of electrochemical mediators to be formed without processing mediated electrochemical The place of matter, the current range so as to set electrochemical mediators and the current range without handling electrochemical mediators, from And it can identify electric current selectively to show wet place and location and degree.Such as processing has electrochemical mediators Current range is 0.1- 5A, has the current range of electrochemical mediators that can be less than 0.1A without handling.This when, this when, Although the part for not handling electrochemical mediators is wet, is also generated with electric current, will not cause to alarm, on the contrary, if Electric current between two conducting wires is greater than 0.1A, then it is assumed that is that processing has the place of electrochemical mediators to be wet, then causes to report It is alert, to indicate to be wet.

In some embodiments, substrate is hydroscopic paper band.Such as filter paper, rice paper, vegetation fibrous absorbent paper have good Hygroscopicity, the paper wood that liquid will not be spread wantonly is used equally for doing substrate.

In some embodiments, as shown in figure 12, substrate is wide ribbon hydroscopic paper, and humidity detection unit S is along base The length direction of material is spaced apart.Electrode plate in the portion S can arrange arbitrarily, have a certain distance between every two electrode plate and It does not contact, but handles electrochemical mediators on electrode plate, then carry out drying and processing.Which mediated electrochemical has not been handled at The part of matter, such as the local of 989 and 981 marks of Figure 12 also have conductive coating process, even if but on 989 and 981 ground Side is wet, and conductive coating will not be allowed to form a circuit, there will be no the generations of electric current, there will not be the production of signal It is raw.Only the position S just will form a circuit after being wet, to generate signal.This is only an opposite state, just As said before, it is different with the electric conductivity without handling electrochemical mediators that electrochemical mediators have been handled, so as to generate not With electric current or voltage, allow equipment can distinguish out it is also possible, such as only processing have electrochemical mediators Part forming circuit just carries out the prompt of signal, even if opposite non-process has the part of electrochemical mediators to be connected also without signal Prompt.

As a kind of scheme, as shown in Fig. 1,3,5,6,8,9, there is at least one bulb on substrate；Bulb has wet Degree test section S is spaced setting in the width direction.

Optionally, it is good material which hygroscopicity substrate, which can also choose not, or even does not have hygroscopicity, such as plastics Thin slice, but have the place of electrochemical mediators in processing, have hygroscopicity can.Because processing has the ground of electrochemical mediators There are two electrodes for side's arrangement.As long as the electrochemical mediators encounter hydrone, electrochemical solution is partly or entirely formed, so as to cause It is conductive.

In some embodiments, the coated conducting wire as shown in Fig. 1,3,5,6,8,9,12 has more to coated conducting wire, coated conducting wire Between without intersection.All coated conducting wires are located on the same floor, and without intersection point between coated conducting wire, therefore are not in signal interference.

In some embodiments, as shown in figure 12, coated conducting wire extends along the length direction of substrate.Outermost two Conducting wire is respectively the straightway parallel with substrate.Each wire has the parallel-segment parallel with substrate.One end of parallel-segment is letter Number terminal.Signal terminal is for accessing electric current.It is numbered from first coated conducting wire to a last coated conducting wire with natural number, phase There is humidity detection unit S between adjacent odd number conducting wire, alternatively, having humidity detection unit S between adjacent even number conducting wire.In this way, To the area utilization highest of substrate, each conducting wire is efficiently used, obtains the humidity detection unit S of most quantity, improves humidity Detection range.
