[description of drawings]
Fig. 1 is the structural representation based on the information acquisition device of Internet of Things that the embodiment of the invention provides.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
See also Fig. 1, the structural representation that Fig. 1 provides for the embodiment of the invention based on the information acquisition device of Internet of Things.
The information acquisition device that the embodiment of the invention provides comprises substrate 11 and at least two information detectors 12.
In embodiments of the present invention, information detector 12 is an electrochemical sensor, can certainly be the detecting device of other suitable forms, does not enumerate one by one here.
Wherein, information detector 12 is integrated on the substrate 11 through nanometer or micro-nano technology, is used to obtain the information of determinand.
Micro-nano technology is that (micro-electro-mechanical system is MEMS) with the abbreviation of nanoscale science and technology for micro electro mechanical system (MEMS) technology.Micro electro mechanical system (MEMS) technology relates generally to 0.1 micron research and development to interior sensor, microactrator and micro-system of number mm-scale scope; MEMS is stock with monocrystalline silicon; Be fabricated to main processing characteristic so that photoetching is parallel, adopt microelectronic technique equipment to combine other special process equipment as manufacturing process.
In the practical implementation process, the information of thing to be detected comprises the temperature of thing to be detected, humidity, environmental stress etc., can also be the trace toxic gas in daily necessities and the food, and perhaps relevant with consumer self medical treatment detects, such as blood sugar concentration etc.
Preferably, when information detector 12 was electrochemical sensor, it further can be in the electric potential type sensor in the electrochemical sensor, amperometric sensor or the conductivity type sensor one or more.Wherein, information detector 12 comprises electrode, film, electrolyte and filtrator.
Wherein, the electric potential type sensor will be dissolved in ionization in the electrolyte solution in ion electrode, and then the electromotive force that produces, and electromotive force removed as the output of sensor, thereby realized the detection of ion;
It is a constant current potential that amperometric sensor keeps the interface of electrode and electrolyte solution, and with measured object direct oxidation or reduction, and the electric current that will flow through external circuit removes as the output of sensor, thus the detection of realization chemical substance;
The variation that the conductivity type sensor is put upside down with measured object oxidation or reduction back electrolyte solution is taken out as the output of sensor, thereby realizes the detection of material.
The embodiment of the invention can realize the detection of multi-field determinand according to user's demand, for example:
A, temperature humidity detect;
B, gas componant detect: like formaldehyde, and carbon monoxide, ammonia etc.;
C, gas concentration detect: like oxygen concentration, and gas concentration lwevel etc.;
D, solid-state and fluent meterial detection: like melamine, methyl alcohol, trench wet goods;
E, health index detect: like blood sugar, and blood fat etc.
See also Fig. 2, Fig. 2 shows the structure of electrod-array in the electrochemical sensor that the embodiment of the invention provides.
Electrochemical sensor includes a plurality of electrod-arrays, and electrod-array comprises electrode 21, semiconductor film 22, temperature sensor 23 and go between 24.Wherein, semiconductor film 22 can be sensitive membrane such as metallic nano-particle, conducting polymer or oxide.
In the practical implementation process, electrod-array is encapsulated in the box of band filtrator, and 24 is connected with external circuit through going between.When detecting; Detected gas is diffused into the chemical reaction ejected electron takes place on the semiconductor film 22; Make the impedance of semiconductor film 22 change,, so can measure the variable of impedance through metering circuit because the impedance variations of molecular number and the semiconductor film 22 of gas value is linear within the specific limits; Replenish the variable quantity measure gas molecule through temperature again, and then obtain the concentration etc. of determinand.
Wherein, electrochemical sensor being integrated in 11 last times of substrate, be example with the ito glass substrate; At first on the ito glass substrate, coat photoresist, will have the ito glass substrate photoetching of photoresist, carve the electrode groove; Metal (Pt) is splashed on the substrate 11, forms metal level, remove photoresist and ito glass rete then; Remaining metal is coated semiconductor film and oven dry as chemical electrode on glass substrate, form the electrod-array sensor.
The embodiment of the invention also provides a kind of information acquisition apparatus based on Internet of Things, and this information acquisition apparatus comprises the information acquisition device that the embodiment of the invention provides, and in view of this device has detailed description at preceding text, repeats no more here.
