Flexible printing fecaluria sensorTechnical field
The present invention relates to sensor technical field, a kind of flexibility specifically, can print the fecaluria sensor of preparation.
Background technology
Sensor, as the extension of mankind's sense organ, is the primary link that detects and control, and has obtained people's extensive attention. The sensor that can change into electrical quantities (such as voltage, resistance, electric capacity, inductance etc.), is especially conveniently applied in intellectuality, in the future life of networking. The sensor existing on the market at present, from function, kind, sees varied, varied in preparation technology. Existing sensor almost can be measured random physical quantity, and is measuring sensitivity, precision, and the aspects such as repeatability have reached quite excellent degree. The performance of sensor is not more excellent better, and in the situation that meeting set needs, people often more consider the cost of sensor, volume, other non-functional factor of grade easy to use.
Here we solve a minor issue: infant's diaper, adult diaper the inside have or not fecaluria excreta, then change into detectable electrical quantities, send signal detection circuit to. Existing can have much for the sensor of this kind of situation, such as: various water sensors, urea sensor, humidity sensor etc. Existing sensor exists some problems, as: cost is high, and volume is large, use inconvenience. In other words, people only need sensor to tell that fecaluria is excremental to be had or nothing, and not needing to know has how many amounts; People more want sensor cheapness, preferably disposable, throwaway; People more want sensor bulk little, are easy to be placed on diaper, paper diaper the inside; People more want the installation of sensor, do not affect snugness of fit. Therefore the precision of fecaluria sensor and repeatability have not been very crucial, and people more take a fancy to cheapness, and volume is little, easy to use and comfortable.
In prior art, CN201410003566 Chinese patent application discloses a kind of bolt type water sensor, comprises the insulation isolated material of filling between the first metallic conductor, the second metallic conductor and metallic conductor. But, the sensor function singleness, be three-dimensional bolt type, manufacturing process complexity, cost high, can not facilitate and cosily use.
In view of this, be necessary to provide a kind of flexible printing fecaluria sensor to address the above problem.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is described in detail, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to the scope of protection of the invention.
Fig. 1 is the schematic diagram of flexible printing fecaluria sensor in the specific embodiment of the invention. Shown in ginseng Fig. 1, in present embodiment, the schematic diagram of flexible printing fecaluria sensor, comprises fexible film substrate 11, printing conductive electrode 12, sensitive zones 13. Wherein, the material of fexible film substrate 11 can be: paper, polymer, inorganic matter, natural fibre products, metal, composite. Fexible film substrate 11 is as printed substrates, in order to support the electrode part 12 of sensor, and functional material. Printing conductive electrode 12, can use: the metal pastes such as silver-colored slurry, aluminium paste, copper slurry, gold paste, can be also: electrically conducting transparent slurry, conducting polymer, doping inorganic semiconductor material etc. Typography can be: serigraphy, bat printing, transfer printing, chromatography, gold stamping, intaglio printing, letterpress, nano impression, without mask print, ink jet printing. Printing conductive electrode 12 is as the electrode of sensor, for the realization of sensing function and the conduction of the signal of telecommunication. Printing conductive electrode 12, at attachment region 13 places of functional material, is designed with the sensing electrode 14 of prong shape.
